Costco pork loin chops deserve better than basic pan-searing—they transform into a restaurant-worthy centerpiece with crispy edges and tender centers. I've perfected this one-pan garlic-herb method after years of cooking through entire Costco packs, and it delivers foolproof results every time.
The secret lies in high-heat searing followed by low-and-slow roasting, which creates that coveted crust while keeping the interior juicy.
This recipe starts with proper prep—trimming any excess fat from those generous Costco chops and creating a simple garlic-herb crust that seals in moisture. We'll use a single cast-iron skillet for both searing and roasting, minimizing cleanup while maximizing flavor.
The aromatic blend of rosemary, thyme, and garlic infuses the meat deeply during cooking, creating layers of complexity that balance the pork's natural richness.
By the time you're done, you'll have perfectly cooked pork loin chops with golden-brown, crispy edges that give way to tender, juicy meat inside. The garlic-herb crust adds depth without overpowering, and the one-pan method ensures everything stays hot and delicious.
This is the kind of weeknight dinner that feels special without requiring hours in the kitchen.
Pair with roasted potatoes or a crisp apple salad to complete the meal. The leftovers reheat beautifully too, making this perfect for meal prep. Let's get cooking—your taste buds will thank you for this upgrade from basic pork chops to showstopping centerpiece.
Ingredients for costco pork loin chops
Costco pork loin chops need just 11 ingredients to become restaurant-quality centerpiece with crispy edges and juicy centers.
| Ingredient | Amount | Notes |
|---|---|---|
| Costco Pork Loin Chops 🥩 | 12 whole | Bone-in, 1-inch thick, excess fat trimmed |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High smoke point for searing |
| Fresh Rosemary 🌿 | ¼ cup | Finely chopped, stems removed |
| Fresh Thyme Leaves 🌿 | ¼ cup | Or 1 tbsp dried thyme |
| Garlic Cloves 🧄 | 10 cloves | Minced, not powdered |
| Diamond Crystal Kosher Salt 🧂 | 2 tbsp | Plus extra for seasoning |
| Freshly Ground Black Pepper 🌶️ | 1 tbsp | Cracked peppercorns preferred |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for basting |
| Fresh Lemon 🍋 | 1 whole | Zested and juiced |
| Heavy Cream 🥛 | ½ cup | For pan deglazing |

The pork chops are the star, so grab the Costco pack—they're thick-cut and bone-in, which gives you that perfect crust-to-tender ratio. Trim any excess fat (it's not bad, but you want even cooking), and pat them dry with paper towels—this helps the crust form. Trader Joe's often has great fresh herbs if your grocery store's selection is lackluster. For the garlic, I always grab the bulk cloves and peel them myself—they're fresher than pre-minced. The rosemary should smell piney and vibrant, not dusty. If your bunch is wilted, give it a quick soak in cold water for 10 minutes to revive it.
No fresh rosemary? Dried works at one-third the amount, but the flavor won't be as bright. Short on heavy cream? Half-and-half or whole milk will work in a pinch, though the sauce won't be as rich. The butter is crucial here—use unsalted and keep it cold when cubing it for basting. For the lemon, I always buy the thick-skinned varieties from Whole Foods (like Eureka or Meyer)—they're juicier and last longer. If you're prepping ahead, trim and season the chops up to 24 hours early, but don't marinate them—they'll get too mushy.
These chops reheat beautifully—just 5 minutes at 350°F wrapped in foil. Store leftovers in the fridge for 4 days or freeze for 3 months in an airtight container. I like to portion them with their pan juices for extra flavor. The herbs can be chopped ahead and stored in the fridge for 3 days in a sealed container. For meal prep, double the batch—they're perfect for lunches or dinner leftovers. The pan sauce freezes well too, so save it for future meals.

Step-by-step instructions for Costco pork loin chops recipe
Here's how to transform Costco pork loin chops into a restaurant-worthy one-pan masterpiece.
Create the Herb Garlic Marinade
In a small bowl, combine the 0.5 cup extra-virgin olive oil, 0.25 cup finely chopped fresh rosemary, 0.25 cup fresh thyme leaves, 10 minced garlic cloves, 2 tablespoons diamond crystal kosher salt, and 1 tablespoon freshly ground black pepper. Mix thoroughly until the herbs are well coated and the mixture emits an intoxicating aroma. This marinade will infuse the pork with deep, aromatic flavors while preventing dryness during cooking.
Let the marinade sit at room temperature for 10 minutes while you prepare the chops. The brief resting time allows the flavors to meld together, creating a cohesive base that will transform the pork's natural mildness into something extraordinary. This step ensures every bite carries that perfect balance of garlic, herbs, and salt.
Sear the Chops for Maximum Flavor and Crisp
Preheat your oven to 425°F. In a large oven-safe skillet, add the 0.5 cup unsalted butter and place it over medium-high heat. Once the butter begins to foam (about 2 minutes), carefully add the pork loin chops in a single layer, making sure they don't overlap. Cook undisturbed for 3-4 minutes per side until the edges turn a beautiful deep golden brown and the internal temperature reaches 145°F on an instant-read thermometer.
This high-heat sear creates a flavorful crust that locks in juices, while the butter basting ensures those crispy edges we're after. Don't rush this step—patience here makes all the difference. The butter should bubble vigorously, creating a rich, aromatic foam that will baste the chops as they cook.
Roast to Juicy Perfection
Transfer the skillet to the preheated oven and roast for 12-15 minutes until the internal temperature reaches 155°F. The chops should be tender yet still slightly firm to the touch. During this time, the marinade will caramelize slightly, creating a glossy finish on the chops that signals perfect doneness.
Here's where the magic happens: the oven's dry heat finishes cooking the chops while the residual butter and marinade continue to baste them. This dual-action cooking method guarantees juicy meat with that coveted crispy exterior. The 155°F internal temperature ensures the pork is fully cooked while maintaining its natural moisture.
Deglaze and Finish with Lemon Cream Sauce
Remove the chops from the oven and transfer them to a warm serving platter. Increase the skillet's heat to medium and add the 0.5 cup heavy cream, scraping up all the browned bits from the bottom with a wooden spoon. Stir in the zest and juice of 1 whole fresh lemon and simmer for 2-3 minutes until the sauce slightly thickens. The sauce should coat the back of a spoon with a velvety texture.
This deglazing step captures all the flavorful fond from the searing process, transforming it into a luxurious sauce that complements the herb-infused pork. The lemon brightens the rich flavors, creating a perfect balance. Keep the sauce warm while you prepare the final garnish.
Garnish and Serve Immediately
Spoon the lemon cream sauce over the pork chops and garnish with 0.15 cup chopped fresh parsley. The parsley adds a fresh, vibrant contrast to the rich, caramelized flavors. Serve immediately while the chops are still piping hot, with the sauce pooling attractively around each chop.
Each bite should deliver perfectly balanced flavors: crispy edges that give way to tender, juicy meat infused with garlic and herbs, all finished with a bright lemon-cream sauce. The chops should be golden brown with a crisp exterior that contrasts beautifully with the tender interior. Serve with roasted potatoes or a fresh green salad to complete this impressive one-pan meal.
Pro Tips For Making Costco Pork Loin Chops
- SEAR THEM HARD: Costco pork loin chops are lean—don’t be shy with the olive oil and heat. Get a screaming-hot pan and let those chops develop a deep golden crust before you even think about adding herbs. I used to rush this, and the result was dry, sad meat. Two minutes per side, no less.
- MINCE THAT GARLIC: Skip the whole cloves pressing into the meat—it looks pretty but doesn’t cook evenly. Instead, finely mince the garlic (a knife works fine) and mix it into the olive oil before searing. It’ll bloom flavor faster and stick to the chops like glue. Trust me, your knife will thank you later.
- SALT THE CHOPS FIRST: Season the pork loin chops before they hit the pan—at least 30 minutes ahead if you can. The salt needs time to work its magic and draw out moisture, which you’ll wipe away right before cooking. I learned this the hard way when my chops ended up sticking like glue.
- REST THEM UNDER FOIL: After pulling the chops off heat, tent them loosely with foil and let them sit for 5 minutes. This keeps the juices from running out when you cut into them. I know, it’s tempting to serve them immediately—but that’s how you end up with dry, stringy meat. Just wait.
Best sauces and condiments for this costco pork loin chops
Classic Garlic-Herb Sauce
The lemon cream sauce we make from the pan drippings is where this dish truly shines. After searing the chops, I deglaze the skillet with ½ cup heavy cream and add zest and juice of 1 lemon—this brightens the rich pork flavors beautifully.
The sauce should coat the back of a spoon with a velvety texture, not be watery. For extra depth, I sometimes add 1 tsp Dijon mustard to the sauce before finishing with the lemon. 🍋
Apple Cider Glaze
For a sweet-tangy twist, swap the lemon cream sauce for an apple cider glaze. Simmer ½ cup apple cider with 1 tbsp brown sugar and ½ tsp cinnamon in the skillet after removing the chops.
Reduce by half, then finish with 1 tbsp butter for shine. This works especially well with the crispy chops and complements the pork's natural sweetness. I've used this glaze for holiday dinners—it's a crowd-pleaser!
Spicy Honey Mustard
When I want to add some heat, I make a quick spicy honey mustard sauce. Mix ¼ cup Dijon mustard, 2 tbsp honey, 1 tbsp apple cider vinegar, and ½ tsp cayenne pepper in the skillet after cooking.
Thin with 1-2 tbsp warm water if needed. This sauce cuts through the richness of the pork beautifully and adds a nice contrast to the crispy edges. I keep a bottle of Penzeys hot honey on hand for this exact purpose!
Brown Butter Pan Sauce
For maximum richness, don't remove all the butter after searing. Instead, let it brown completely in the skillet after removing the chops, then whisk in ¼ cup chicken stock and 1 tbsp cold butter to finish. The nutty brown butter flavor adds incredible depth to the dish.
This method works especially well if you're serving the chops with roasted vegetables—the sauce will complement everything on the plate. I often use this technique when cooking for large groups.
Herb-Infused Olive Oil
For a lighter option, drizzle the chops with 2 tbsp infused olive oil instead of sauce. Heat ½ cup olive oil with 2 sprigs rosemary, 2 sprigs thyme, and 2 garlic cloves until fragrant, then strain. This oil adds a fragrant finish without overpowering the dish.
I like to serve this with grilled asparagus or a simple arugula salad for a lighter meal. The oil keeps well in the fridge for up to 1 week.
Balsamic Reduction
When I'm feeling fancy, I make a quick balsamic reduction to drizzle over the finished chops. Simmer ¼ cup balsamic vinegar in the skillet after cooking until reduced by half, then finish with 1 tsp butter.
The tangy sweetness of the reduction cuts through the richness of the pork beautifully. I recommend using a high-quality balsamic like San Marzano balsamic glaze for the best results. This works particularly well with the crispy edges of the chops. 🍷

Frequently asked questions
How do I trim the fat from Costco pork loin chops?
Use a sharp knife to carefully slice away any thick fat deposits, leaving about ¼-inch of fat for flavor. Focus on the edges and thickest parts—this helps create even cooking and prevents greasy edges. The chops should have a clean, even surface for maximum crispiness. Never remove all fat, as it contributes to moisture and flavor during cooking.
Can I cook these chops without an oven?
Yes! For stovetop-only cooking, sear the chops in a heavy skillet over medium-high heat for 4-5 minutes per side until golden. Then reduce heat to medium-low and cover with a lid for 8-10 minutes until internal temp reaches 155°F. Finish with the lemon cream sauce as directed. The texture will be slightly less crispy but still delicious.
What's the best way to reheat leftovers?
Warm leftovers in the oven at 350°F for 5-8 minutes wrapped in foil with a splash of water or broth to prevent drying. For microwave reheating, use 30-second intervals on medium power, checking between each. Always let chops rest 5 minutes after reheating to redistribute juices. The pan sauce reheats beautifully too—simmer gently for 2-3 minutes.
Why did my chops turn out dry?
Most likely, they were overcooked or didn't rest properly. Use an instant-read thermometer to monitor 155°F internal temp, and always let chops rest 5-10 minutes before slicing. Another common mistake is cutting into them too soon—the juices need time to redistribute. For extra moisture, try brining the chops for 30 minutes before cooking.
What sides pair best with these pork chops?
Roasted garlic mashed potatoes or crispy roasted fingerling potatoes are perfect matches. For lighter options, try a shaved fennel and orange salad or grilled asparagus with lemon. The crispy edges of the chops pair beautifully with creamy textures or bright acidity from vinegar-based sides.
