What Kind of Lamb Chops Should I Use?

For this recipe, you’ll want lamb shoulder chops.

Shoulder chops are different from the smaller lamb rib or loin chops that are typically cooked quickly over high heat.

Because the shoulder is a harder-working cut of meat, it benefits from longer, slower cooking. That makes lamb shoulder chops perfect for this recipe, where they gently roast in tomatoes, vegetables, herbs, and warm spices.

The result is a rich, hearty lamb dish that’s perfect for a cozy dinner.

Ingredients You’ll Need

Lamb Shoulder Chops

You’ll need four lamb shoulder chops. Look for chops with good marbling, which adds flavor and helps keep the meat juicy as it cooks.

Butternut Squash

Butternut squash adds subtle sweetness that works beautifully with the savory lamb and warm spices.

Cut the squash into relatively small, evenly sized cubes so it cooks through during roasting.

Onion

Sliced onion creates the savory base of the dish and becomes wonderfully soft as everything slowly cooks together.

Whole Plum Tomatoes

A 28-ounce can of whole plum tomatoes creates the rich tomato sauce that surrounds the lamb.

I like to break the tomatoes apart slightly while stirring so you still have some texture in the finished sauce.

Fresh Garlic

Fresh chopped garlic adds another layer of savory flavor to the sauce.

Fresh Thyme

Thyme and lamb are such a classic combination. Its earthy flavor works especially well with the warm spices in this dish.

Cumin

Cumin adds a deep, earthy warmth and is one of the predominant spices in this recipe.

Cinnamon

A small amount of cinnamon gives the sauce warmth without making it taste sweet.

Allspice

Allspice adds warm, slightly peppery flavor that complements both the lamb and butternut squash.

And despite its name, allspice is actually one spice—not a blend of several spices.

Oregano

A little oregano rounds out the herbs and spices.

Fresh Parsley

Fresh parsley adds color and freshness to the finished dish.

How to Make Slow Roasted Lamb Chops

Step 1: Sauté the Vegetables

Preheat your oven to 280°F.

Heat one tablespoon of olive oil in a large Dutch oven over medium-high heat.

Add the sliced onion and diced butternut squash and sauté for about 5 minutes, stirring occasionally, until the onion begins to soften and the squash starts to brown slightly.

Transfer the vegetables to a plate and set aside.

Step 2: Sear the Lamb Chops

Add another drizzle of olive oil to the Dutch oven if needed.

Add the lamb shoulder chops and sear until nicely browned on both sides.

Don’t rush this step! Browning the lamb adds another layer of flavor to the finished dish.

Transfer the lamb to a plate and set aside.

Step 3: Build the Tomato Sauce

Reduce the heat slightly and add the chopped garlic to the same Dutch oven.

Cook for about 30 seconds, stirring constantly, until fragrant.

Add the whole plum tomatoes and their juices, breaking the tomatoes apart slightly with a wooden spoon.

Stir in the fresh thyme, parsley, cumin, cinnamon, allspice, and oregano.

Step 4: Add Everything Back to the Pot

Return the sautéed onion and butternut squash to the Dutch oven.

Nestle the browned lamb chops into the tomato mixture and spoon some of the sauce over the top.

Step 5: Cover and Slow Roast

Cover the Dutch oven with an oven-safe lid and transfer it to the preheated oven.

If your Dutch oven doesn’t have an oven-safe lid, cover it tightly with aluminum foil.

Slow roast for about 1 hour, or until the lamb is tender and the butternut squash can easily be pierced with a fork.

The exact cooking time can vary depending on the thickness of your lamb chops and the size of your butternut squash pieces. If either needs more time, cover the pot again and continue roasting until tender.

That covered-pan clarification is worth making explicit because readers have asked about it, and your original response confirmed that you cover the pan during roasting.

Step 6: Serve

Carefully remove the Dutch oven from the oven.

Taste the tomato sauce and adjust the seasoning if needed.

Finish with additional fresh parsley and serve the lamb chops hot with plenty of the tomato, onion, and butternut squash mixture spooned over the top.

Tips for Tender Slow Roasted Lamb Chops

Use lamb shoulder chops. This recipe is designed for shoulder chops, which benefit from slow cooking.

Don’t skip the sear. Browning the lamb before roasting creates a deeper, richer flavor.

Cut the butternut squash into smaller pieces. This is important. Large pieces can take considerably longer to become tender at the low roasting temperature.

Don’t burn the garlic. It only needs about 30 seconds in the pan before you add the tomatoes.

Keep the Dutch oven covered. Trapping the moisture inside helps the lamb gently cook in the tomato sauce.

Use tenderness as your guide. Lamb chops vary in thickness, so don’t rely solely on the clock. If the lamb or squash isn’t tender after an hour, continue cooking it covered.

One reader specifically reported that larger squash pieces weren’t done after the original one-hour cooking time, so this clarification should help prevent the same issue.

Easy Substitutions & Variations

One of my favorite things about reading the comments on this recipe over the years is seeing all of the different ways you’ve made it your own.

No butternut squash? Try sweet potatoes, pumpkin, or another firm winter squash.

You can also add vegetables such as carrots or green beans to make the dish even heartier. If you’re adding a quick-cooking vegetable like green beans, add them later in the cooking process so they don’t become too soft.

Readers have successfully made this recipe with kumara (sweet potato), pumpkin, carrots, and green beans.

Tools You’ll Need

You don’t need much special equipment for these slow roasted lamb chops, but these are a few kitchen tools that make preparing the recipe easier.

Dutch Oven — Perfect for searing the lamb, building the sauce, and transferring everything directly into the oven.

Chef’s Knife — A good sharp knife makes prepping the onion and cutting the butternut squash much easier.

What to Serve With Slow Roasted Lamb Chops

This is such a hearty dish that it can absolutely stand on its own, but that rich tomato sauce is practically begging for something underneath it.

My favorite is basmati rice because it soaks up all of that tomato sauce.

You can also serve these lamb chops with:

• Couscous
• Creamy mashed potatoes
• Polenta
• Roasted potatoes
• Crusty bread

For something lighter, add a simple green salad or roasted vegetables.

Can I Make Slow Roasted Lamb Chops Ahead of Time?

Absolutely.

In fact, this is a great dish to make ahead because all of those spices, tomatoes, and lamb have even more time to come together.

Prepare the recipe completely and allow everything to cool before transferring it to an airtight container and refrigerating.

When you’re ready to serve, gently reheat the lamb and sauce in a covered Dutch oven or skillet until warmed through.

How to Store & Reheat Leftovers

Allow leftover lamb chops and sauce to cool before transferring them to an airtight container.

Store leftovers in the refrigerator for up to 3–4 days.

To reheat, place the lamb and plenty of its tomato sauce in a covered skillet or Dutch oven over low heat until warmed through.

Keeping the lamb surrounded by sauce while reheating will help prevent it from drying out.

Frequently Asked Questions

Should I cover lamb chops while roasting?

Yes. For this recipe, you want to keep the Dutch oven covered.

The lid traps moisture inside and allows the lamb to gently slow roast in the tomato sauce.

If you don’t have an oven-safe lid, tightly cover your pan with aluminum foil instead.

Why isn’t my butternut squash tender?

The size of the squash pieces makes a big difference.

Cut the butternut squash into relatively small, evenly sized cubes and sauté it before adding it to the Dutch oven.

If the squash still isn’t fork-tender after an hour, simply cover the pot again and continue roasting until it is.

Can I use sweet potatoes instead of butternut squash?

Yes! Sweet potatoes are a great substitute.

You can also use pumpkin or another firm winter squash.

Can I use lamb loin chops instead?

I recommend sticking with lamb shoulder chops for this recipe.

Loin and rib chops are naturally more tender and generally better suited to quick, high-heat cooking. Shoulder chops benefit from the longer, slower cooking method we’re using here.

Is allspice a blend of spices?

No. This is a common misconception!

Despite its name, allspice is a single spice made from the dried berries of the Pimenta dioica plant.

What can I substitute for allspice?

If you don’t have allspice, you can leave it out and adjust the other warm spices to your taste.

The flavor won’t be exactly the same, but the lamb will still be delicious.

Can I cook the lamb at a higher temperature?

You can cook lamb shoulder using other methods and temperatures, but this particular recipe was developed around a low-and-slow roast at 280°F.

Because your lamb chops can vary in thickness, use tenderness rather than time alone to determine when they’re ready.
