Garlic Herb Lamb Chops – Easy 50-Minute Dinner

Garlic Herb Lamb Chops with Cheddar Mashed Potatoes & Asparagus is the dinner I make when I want people to think I've been secretly training under a French chef. Spoiler: I haven't. I just know how to sear a chop and boil a potato, and by the end of this post, so will you.

Here's the analogy I use with friends learning to cook: lamb chops are like a good handshake. Too limp and it's awkward, too aggressive and it's painful, but a firm, confident one leaves everybody smiling. We're going for a confident handshake here: a hard sear outside, blush-pink inside, and a quick herb-garlic butter bath at the end.

Meanwhile, the potatoes get mashed with sharp cheddar (yes, cheddar in mashed potatoes, trust me), and the asparagus roasts in the same hot oven until the tips go crispy and the stalks stay snappy. One hour, three components, zero takeout menus.

About the Ingredients

8 bone-in lamb loin chops, about 1 inch (2.5 cm) thick (roughly 2 lb / 900g total)

Loin chops are the sweet spot between tender and affordable. If you can only find rib chops, buy 12 and shave 1 minute off each sear side. Look for bright pink meat and white fat, not gray.

2 lb (900g) Yukon Gold potatoes, peeled and cut into 1-inch chunks

Yukon Golds mash creamy without turning gluey. Russets work too but get starchier, so add an extra splash of milk. Skip waxy red potatoes here; they stay lumpy.

1 1/2 cups (170g) sharp white cheddar, freshly grated

Grate it yourself off a block. Pre-shredded cheddar is dusted with anti-caking starch and melts grainy. White cheddar is sharper and less orange, but yellow sharp cheddar is a fine swap.

1 lb (450g) fresh asparagus, woody ends snapped off

Snap one stalk to find the natural break point, then line the rest up and cut there. Thin spears roast faster; thick spears need 3 extra minutes. Frozen asparagus will steam rather than crisp, so use fresh if you can.

6 cloves garlic, 4 minced for the chops and 2 smashed for the potatoes

Fresh garlic only, please. Jarred garlic tastes flat and slightly metallic. If you're garlic-shy, use 4 cloves total and nobody will complain.

6 tbsp (85g) unsalted butter, divided (3 tbsp for chops, 3 tbsp for potatoes)

Unsalted lets you control the seasoning since cheddar is already salty. Ghee or a good olive oil works for the chops if you're dairy-free on the meat but keep butter for the potatoes.

2 tbsp fresh rosemary and thyme, finely chopped (about 1 tbsp each)

Dried herbs are 3x stronger by volume, so use 2 tsp total if that's what you have. Strip thyme leaves by pulling the stem backward through your fingers.

1/2 cup (120ml) whole milk or half-and-half, warmed

Warm dairy keeps mashed potatoes hot and fluffy; cold milk shocks them and makes them gluey. Oat milk or heavy cream both work, just warm whatever you choose.

3 tbsp olive oil, plus more for drizzling

Regular olive oil is perfect for high-heat searing. Save the fancy finishing oil for salads. Avocado oil is an even higher smoke-point swap.

1 1/2 tsp kosher salt, divided, plus more to taste

Kosher salt flakes are bigger and less salty by volume than table salt. If using table salt, cut each measurement by about a third.

1 tsp freshly cracked black pepper, divided

Crack it fresh; pre-ground pepper tastes like dust. A coarse grind gives you little bursts of heat instead of an even burn.

Tips & Tricks

Bring the Chops to Room Temperature

Cold lamb hits the pan and steams instead of searing. Pull them out 25 to 30 minutes before cooking so the center cooks evenly.

Salt the Chops Early

Season them right when they come out of the fridge. That 25-minute rest lets the salt absorb instead of sitting on the surface.

Don't Crowd the Pan

If your skillet can't fit all 8 chops with space between them, sear in two batches. Crowding drops the pan temperature and you'll boil the meat.

Rest Before Slicing

Give the chops 5 minutes on a board. Cut too soon and the juices run onto the plate instead of staying in the meat.

Step-by-Step Instructions

1. Preheat and Prep

Heat your oven to 425F (220C) and line a sheet pan with parchment. Pat the lamb chops completely dry with paper towels, then season both sides with 1 tsp kosher salt and 1/2 tsp pepper. Let them sit at room temperature while you start the potatoes.

2. Boil the Potatoes

Place the potato chunks in a large pot and cover with cold water by 2 inches. Add the 2 smashed garlic cloves and 1 tsp salt. Bring to a boil over high heat, then reduce to a steady simmer and cook 15 to 18 minutes, until a knife slides in with zero resistance.

3. Roast the Asparagus

While the potatoes boil, toss the asparagus on the sheet pan with 1 tbsp olive oil, 1/4 tsp salt, and 1/4 tsp pepper. Spread in a single layer and roast at 425F (220C) for 10 to 12 minutes, until the tips are browned and a stalk bends without snapping. The tips should look slightly shriveled and crisp at the edges.

4. Mash with Cheddar

Drain the potatoes and discard the garlic cloves. Return them to the hot pot for 1 minute to dry out. Add 3 tbsp butter and the warmed milk, then mash until smooth. Fold in the grated cheddar, taste, and season with salt. Keep covered and warm.

5. Sear the Lamb Chops

Heat 3 tbsp butter and 2 tbsp olive oil in a large skillet over medium-high heat until the butter foams and smells nutty, about 2 minutes. Lay in the chops without crowding and sear 3 to 4 minutes per side, until deeply golden brown and an instant-read thermometer reads 130F (54C) for medium-rare. The crust should look lacquered, not black.

6. Add Garlic and Herbs

In the final minute of searing, tilt the pan and spoon the foaming butter over the chops. Add the 4 minced garlic cloves and chopped rosemary and thyme, swirling for 30 to 45 seconds until fragrant. Garlic should smell sweet, never bitter. If it darkens, pull the pan off the heat immediately.

7. Rest the Chops

Move the chops to a cutting board and spoon a little of the garlic-herb butter from the pan over each one. Rest 5 minutes. The internal temperature will climb to about 135F (57C) as it rests.

8. Plate and Serve

Spoon a generous mound of cheddar mashed potatoes onto each plate, lean 1 or 2 chops against it, and pile the roasted asparagus alongside. Drizzle the pan drippings over everything and finish with flaky salt. Serve immediately while the butter is still glossy.

Delicious Variations

Greek Twist

Swap the cheddar for crumbled feta and add a squeeze of lemon and dried oregano to the potatoes.

Spicy Harissa Chops

Rub the chops with 1 tbsp harissa paste before searing and skip the rosemary for a smoky North African spin.

Parmesan and Pea Mash

Replace cheddar with grated Parmesan and fold in 1 cup of thawed peas for a springtime version.

👨‍🍳 Chef's Note: A cast-iron skillet gives you the deepest crust on these chops, but any heavy pan will work. If your chops are thinner than 1 inch, sear 2 to 3 minutes per side instead.
