Tender lamb chops come out of the oven best when you account for thickness and desired doneness level. So if you are wondering how long to bake lamb chops in the oven, the short answer is 7 to 12 minutes per side at 425°F for thick chops, and less for thin ones.
This guide breaks down exact times by thickness, doneness, and oven temperature. You will also get a simple step-by-step method that works every time.
How Long To Bake Lamb Chops In The Oven
The bake time depends on three things: how thick your chops are, what internal temperature you want, and how hot your oven runs. Here is a quick reference you can use right away.
- 1 inch thick chops: 10 to 12 minutes total at 425°F for medium rare
- 1.5 inch thick chops: 14 to 18 minutes total at 425°F for medium rare
- 2 inch thick chops: 20 to 25 minutes total at 425°F for medium rare
- Thin chops (under 1 inch): 6 to 9 minutes total at 425°F for medium rare
These times are for bone-in chops. Boneless chops cook a bit faster, so check them 2 to 3 minutes early.
Bake Times By Doneness Level
Use a meat thermometer for the best results. Stick it into the thickest part, away from the bone.
- Rare: 120°F to 125°F
- Medium rare: 130°F to 135°F
- Medium: 140°F to 145°F
- Medium well: 150°F to 155°F
- Well done: 160°F and above
Keep in mind that lamb keeps cooking after it leaves the oven. The temperature can rise 5 to 10 degrees while it rests. So pull the chops out about 5 degrees before your target.
Oven Temperature Matters Too
Most recipes call for 425°F. That heat gives you a nice crust on the outside without drying out the inside.
- 400°F: Add 2 to 4 minutes to the total time
- 425°F: Standard time, good browning
- 450°F: Reduce time by 2 to 3 minutes, watch closely
If you want a softer, slower cook, try 350°F. But then you will need 25 to 30 minutes for thick chops, and the outside won’t brown as much.
Step-By-Step Method For Baking Lamb Chops
Follow these steps and you will get juicy chops with a good sear.
- Take the chops out of the fridge 20 to 30 minutes before cooking. Room temperature meat cooks more evenly.
- Pat them dry with a paper towel. Wet meat steams instead of browning.
- Season both sides with salt, pepper, and any herbs you like. Rosemary, thyme, and garlic work great.
- Preheat your oven to 425°F. Place a cast iron skillet or baking sheet inside while it heats.
- Add a little oil to the hot pan. Sear the chops for 1 to 2 minutes per side on the stove if you want extra color.
- Transfer the pan to the oven. Bake according to the times above.
- Check the internal temperature with a thermometer about 2 minutes before the estimated time.
- Let the chops rest on a cutting board for 5 to 10 minutes before serving.
If you skip the stovetop sear, just put the seasoned chops on a lined baking sheet and roast them. They will still taste good, just with less crust.
How To Tell When Lamb Chops Are Done
A thermometer is the only sure way. But if you don’t have one, here are some visual clues.
- Rare: Soft and squishy, red center
- Medium rare: Slightly firm, pink center
- Medium: Firm but still gives a little, light pink center
- Well done: Very firm, no pink
Cut into one chop near the bone to check. The bone area cooks slowest, so that is the best spot to test.
Common Mistakes That Ruin Lamb Chops
Even good cooks make these errors. Avoid them and your chops will be better.
- Overcooking. Lamb dries out fast past medium. Pull it early and let it rest.
- Not resting the meat. Resting lets the juices settle back into the meat.
- Using a cold pan. A hot pan gives you that nice brown crust.
- Cutting right away. Wait the full 5 to 10 minutes.
- Ignoring thickness. A thin chop and a thick chop need very different times.
Should You Cover Lamb Chops In The Oven?
No, not for most recipes. Leaving them uncovered lets the outside brown. Foil traps steam and makes the meat soggy.
The only time to cover is if the chops are browning too fast on top. Then you can loosely tent them with foil for the last few minutes.
What If Your Chops Are Frozen?
It is best to thaw them first. But if you are short on time, add 50 percent more baking time and lower the heat to 375°F. Check the temperature often so they don’t overcook.
Best Side Dishes And Serving Tips
Lamb chops pair well with simple sides. You don’t need anything fancy.
- Roasted potatoes with rosemary
- Steamed green beans or asparagus
- Couscous or rice pilaf
- A fresh salad with lemon dressing
- Grilled vegetables
Serve the chops right after resting. A squeeze of lemon or a spoon of pan juices adds flavor. If you have leftovers, store them in the fridge for up to 3 days. Reheat gently in a low oven so they don’t dry out.
Quick Recap
For 1 inch chops at 425°F, bake 5 to 6 minutes per side for medium rare. Thicker chops need more time, thinner chops need less. Always use a thermometer and rest the meat before serving. That is the whole secret to perfect lamb chops in the oven.
