Save to Pinterest The first time I made onion jam, my kitchen smelled like a French bistro for three days straight. My roommate kept poking her head in, asking if I was secretly running a restaurant from our tiny apartment. That buttery, caramelized onion scent has a way of making everything feel fancy, even when you're just cooking Tuesday dinner in sweatpants. These lamb chops became my go-to for dinner parties because they look impressive but actually come together faster than you'd think.
I served these at my parents' anniversary dinner last spring, right after I'd discovered balsamic vinegar's magic trick with caramelized onions. My dad, who usually claims to be too full for seconds, went back for thirds. There's something about the way the sharp Dijon cuts through the rich lamb that makes people pause mid-bite and nod appreciatively. Now it's the dish I make when I want to feel like I have my life completely together, even if my kitchen is a mess.
Ingredients
- 8 lamb chops (about 1-inch thick, trimmed): Bone-in or boneless both work, but that thickness helps them stay juicy while getting a gorgeous crust
- 1 tablespoon olive oil: Use something with a neutral flavor so it doesn't compete with the glaze
- 1 teaspoon kosher salt: Diamond Crystal is my go-to for even seasoning
- 1/2 teaspoon freshly ground black pepper: Freshly cracked makes a huge difference here
- 2 tablespoons unsalted butter: Gives the onions that restaurant-quality richness
- 2 large yellow onions, thinly sliced: Take your time with the slicing—uniform pieces caramelize evenly
- 2 tablespoons brown sugar: Helps the onions develop those deep, jammy flavors
- 1/4 cup balsamic vinegar: The secret ingredient that makes everything taste professional
- 2 teaspoons Dijon mustard: Adds just enough sharpness to cut through the sweetness
- 1/2 teaspoon fresh thyme leaves: Earthy and fresh, though dried works in a pinch
- Salt and pepper, to taste: Trust your palate at the end
Instructions
- Prep the lamb:
- Pat those chops completely dry with paper towels—this is crucial for getting a proper sear. Season generously on both sides with the salt and pepper, pressing it in gently so it sticks.
- Sear the chops:
- Heat the olive oil in your large skillet over medium-high until it shimmers. Sear the lamb for 2-3 minutes per side until you've got a beautiful golden brown crust. Remove to a plate and tent with foil to rest.
- Start the onion jam:
- Drop the heat to medium in that same gorgeous fond-filled skillet. Add butter and sliced onions, stirring frequently as they soften and turn golden, about 10-12 minutes.
- Caramelize deeply:
- Stir in the brown sugar and let the onions go another 2-3 minutes until they're a deep, jammy brown. The sugar helps them develop those complex flavors that make this dish special.
- Build the glaze:
- Pour in the balsamic vinegar, Dijon mustard, and thyme. Simmer everything together until it thickens into a glossy glaze, about 2-3 minutes. Season with salt and pepper until it tastes perfect to you.
- Glaze and finish:
- Return the lamb chops to the skillet, spooning that onion jam generously over each one. Cook for 2-3 minutes, turning once, until the chops are heated through and coated in glaze.
Save to Pinterest These became my standby for those nights when I want to cook something that feels like a celebration but doesn't require spending hours in the kitchen. There's something deeply satisfying about watching people take that first bite and go quiet.
Choosing Your Lamb
I've learned that good lamb makes all the difference here. Look for chops with a nice pink-red color and clean white fat—anything that looks grayish or has brown fat is past its prime. American lamb tends to be milder and larger, while New Zealand or Australian lamb has a more pronounced gamey flavor that stands up beautifully to the bold glaze.
Perfecting the Sear
The most common mistake I see is overcrowding the pan. If your lamb chops are touching each other, they'll steam instead of developing that gorgeous crust. Work in batches if you need to—the glaze is quick enough that it won't affect your timing. And please, let them sear undisturbed for those full 2-3 minutes. Moving them around breaks the crust formation.
Make-Ahead Magic
The onion jam can actually be made up to three days ahead and stored in the fridge—it reheats beautifully. In fact, I think the flavors meld and improve overnight. Just warm it gently in a small pan while the lamb sears, then proceed with glazing. This makes the recipe entirely weeknight-friendly.
- Double the glaze recipe and keep the extra in your fridge for quick weeknight meals
- Try this same glaze on pork chops or even roasted chicken thighs
- If serving a crowd, finish the chops under the broiler for 1 minute to set the glaze
Save to Pinterest There's something undeniably elegant about a perfectly cooked lamb chop, but this recipe proves that elegance doesn't have to mean complicated. Enjoy every bite.
Common Recipe Questions

Creamy mashed potatoes, soft polenta, or roasted root vegetables pair beautifully. The sweet glaze also balances well with bitter greens like sautéed kale or arugula salad.
