Keto Lamb Chops with Rosemary Butter is an elegant yet incredibly simple dish that brings together rich, tender lamb and the bold aroma of rosemary-infused butter. Lamb already carries natural fattiness, making it an excellent protein source for anyone following a ketogenic lifestyle.

This recipe takes advantage of minimal ingredients and quick cooking time—perfect for busy evenings, intimate dinners, or meal prep for the week. Rosemary, garlic, and butter create a fragrant and savory blend that enhances lamb’s natural flavor without overpowering it. A cast-iron skillet or grill pan delivers the perfect sear, locking in moisture and fat while adding a smoky, caramelized finish.

One of the reasons this recipe is so popular in low-carb and keto-friendly meal plans is its clean ingredient list and high protein-to-fat ratio. Lamb chops are nutrient-dense, offering essential vitamins like B12, zinc, and iron. The rosemary butter adds healthy fats needed to sustain ketosis while making the meat irresistibly flavorful.

Ingredients
  

  • 8 lamb chops rib or loin chops
  • 3 tablespoons olive oil
  • 4 tablespoons unsalted butter room temperature
  • 3 garlic cloves minced
  • 2 tablespoons fresh rosemary finely chopped
  • 1 teaspoon fresh thyme optional
  • 1 teaspoon sea salt
  • 1 teaspoon black pepper
  • 1 teaspoon smoked paprika
  • ½ teaspoon garlic powder
  • Lemon wedges for serving optional

Equipment

  • 1 Cast-iron skillet or heavy grill pan
  • 1 Knife and cutting board
  • 1 Mixing bowl
  • 1 Tongs
  • 1 Meat thermometer
  • 1 Paper towels
  • 1 Small spoon or silicone spatula
  • 1 Aluminum foil for resting the meat

Method
 

Prepare the lamb chops by patting them dry with paper towels. Removing surface moisture helps achieve a good sear.
  1. Season the lamb generously on both sides with salt, pepper, garlic powder, and smoked paprika. Press seasonings gently so they adhere to the surface.
  2. In a small bowl, combine the softened butter, minced garlic, chopped rosemary, and thyme (if using). Mix until fully incorporated and set aside.
  3. Heat a cast-iron skillet over medium-high heat. Add olive oil and allow it to heat until shimmering but not smoking.
  4. Place the lamb chops into the skillet in a single layer without overcrowding. Sear for 3–4 minutes on one side without moving them.
  5. Flip the chops and cook for another 3–4 minutes on the second side. During the last minute, add the rosemary butter to the pan.
  6. Use a spoon to baste the lamb chops repeatedly with the melted rosemary butter to enhance flavor and moisture.
Check internal temperature using a meat thermometer:
  1. Medium-rare: 135°F (57°C)
  2. Medium: 145°F (63°C)
  3. Well-done: 160°F+ (not recommended for lamb)
Once done, remove lamb chops from the skillet and place them on a plate. Tent loosely with foil and let them rest for 5 minutes.
  1. Serve warm with remaining rosemary butter drizzled on top.

Ingredient Notes (Each Ingredient Fully Explained)

Lamb Chops

You can use rib chops or loin chops. Rib chops are smaller, more tender, and have a curved bone—ideal for searing quickly. Loin chops look similar to a small T-bone steak and offer a slightly meatier bite. Choose chops about 1–1.5 inches thick to ensure they remain juicy inside while achieving a golden crust on the outside.

Olive Oil

Olive oil helps with initial browning and prevents sticking. It also blends well with butter during cooking and adds healthy fats. Choose extra virgin olive oil for superior flavor and quality.

Butter

Butter is the foundation of the rosemary butter mixture. When melted over hot lamb chops, it creates a silky, rich coating that enhances the natural flavor of the meat. Use unsalted butter so you can control overall sodium levels.

Garlic

Fresh minced garlic provides depth, aroma, and savory notes. It caramelizes slightly when mixed with butter, complementing the rosemary and lamb perfectly.

Fresh Rosemary

Rosemary is a classic pairing with lamb. It has a pine-like, earthy aroma that cuts through the richness of the meat. Fresh rosemary works best since dried rosemary can be too brittle and sharp in texture.

Thyme (Optional)

Fresh thyme adds warmth and herbal complexity. If you enjoy a more aromatic profile, include it. If not, it can be omitted without affecting the recipe.

Sea Salt

Enhances natural flavors and helps draw moisture to the surface of the lamb, promoting a crisp sear. Sea salt or kosher salt works better than table salt.

Black Pepper

Adds mild heat and depth. Freshly cracked pepper is recommended for best flavor release during cooking.

Smoked Paprika

This gives the lamb a subtle smokiness and beautiful color. It complements the rosemary butter and adds visual appeal.

Garlic Powder

Provides a secondary layer of garlic flavor without adding moisture. This helps create a balanced seasoning profile.

Lemon Wedges (Optional)

A squeeze of lemon adds brightness and acidity—perfect for cutting through the richness of butter and lamb.

Serving Instructions

  • Pair with keto-friendly sides like cauliflower mash, roasted asparagus, sautéed spinach, or grilled zucchini.
  • Drizzle extra rosemary butter or olive oil on top before serving.
  • Add a squeeze of lemon to brighten flavors.
  • For an elevated presentation, sprinkle fresh rosemary or thyme over the finished dish.

Tips

  • Bring lamb to room temperature for 20–30 minutes before cooking for even browning.
  • Do not overcrowd the skillet—cook in batches if needed.
  • Use a cast-iron skillet for the best sear and heat retention.
  • Rest the meat before serving to allow juices to redistribute.
  • For added richness, add a splash of cream to the pan after searing to create a quick pan sauce.
  • If grilling, preheat the grill to high heat and cook for 3–4 minutes per side.

Storage Information

  • Refrigerator: Store in an airtight container for up to 3–4 days.
  • Freezer: Freeze cooked lamb chops for up to 2 months. Wrap tightly in foil and store in freezer-safe bags.
  • Reheating: Reheat slowly in a skillet over low heat or in the oven at 300°F for 10 minutes. Avoid microwaving, as it can toughen the meat.

FAQs

1. Can I use dried rosemary instead of fresh?

Yes, but use only half the amount because dried rosemary is stronger. Crush it between your fingers to release the aroma before adding.

2. Can I use lamb shoulder chops instead of rib or loin?

Yes, but cooking time will increase. Shoulder chops are tougher and benefit from slower, longer cooking or braising.

3. How do I prevent lamb chops from overcooking?

Use a thermometer and remove them from heat at your desired temperature. They continue cooking slightly while resting.

4. Can I make this recipe dairy-free?

Absolutely. Replace butter with dairy-free butter or olive oil. The flavor will differ slightly but still be delicious.

5. What herbs work well besides rosemary?

Thyme, oregano, parsley, and mint pair beautifully with lamb and can be added to the butter mixture.
