Walking into the lamb section at a grocery store without knowing the difference between loin chops and rib chops is like ordering wine blind. The cuts look similar but cook very differently, and the price gap between them is huge — a rib chop can be $25-30/lb while a shoulder chop can be $8-12/lb. Knowing what you're looking at saves money and prevents disappointed dinners.
Direct Answer
There are four main types of lamb chops sold at retail: rib chops, loin chops, shoulder chops (which include blade chops and arm chops as subtypes), and sirloin chops. **Rib chops** come from the rib section — they look like tiny T-bones with a long bone and a small eye of meat (often 'Frenched' where the fat is scraped from the bone). They're the most tender and most expensive. **Loin chops** come from the loin section — they also look like tiny T-bones but with a larger eye of meat and both tenderloin and strip sections separated by the T-bone. They're very tender and slightly less expensive than rib chops. **Shoulder chops** (also sold as 'blade chops' or 'arm chops') come from the shoulder section — they're less uniform in shape, contain more connective tissue, and are tougher but more flavorful. They cost about a third of what rib chops cost. **Sirloin chops** come from the back of the animal near the leg — they have a round bone in the center and are moderately tender. The price-to-quality ratio of shoulder chops is the best in the category if you cook them right.
The Lamb Anatomy Map
Before identifying chops, understand where each one comes from on the animal. From front to back on a lamb:
1. **Neck** → neck roasts and stew meat (no chops) 2. **Shoulder** → shoulder chops (blade chops and arm chops), shoulder roasts 3. **Rib (rack)** → rib chops, rack of lamb 4. **Loin** → loin chops, saddle of lamb 5. **Sirloin (between loin and leg)** → sirloin chops 6. **Leg** → leg roasts, leg steaks (rarely chops)
The further from the legs and shoulders (the working muscles), the more tender the meat — because those muscles do less work. Rib and loin are the most tender sections. Shoulder and leg are the working muscles and are tougher but more flavorful.
Rib Chops: The Premium Chop
**What to look for**: a single long bone with a small round eye of meat (about 2-3 inches diameter) attached. Typically 1-1.5 inches thick. Often sold 'Frenched' — the fat is scraped from the bone, leaving a clean bare bone handle. A full 'rack of lamb' is 7-8 rib chops still attached; cutting between the bones makes individual rib chops.
**Where to find them**: premium grocery stores, butcher shops, whole rack presentations. Often sold as 'lamb rack' in restaurant settings.
**Price range**: $20-35/lb for Frenched chops. $15-25/lb for regular rib chops. Considerably more at high-end specialty shops.
**How to cook**: fast and hot. Rib chops are tender enough to sear quickly (2-3 minutes per side on high heat) and serve medium-rare. Overcooking is the main risk — by medium-well, they start drying out. Pan sear, grill, or broil. Season simply with salt, pepper, garlic, and rosemary.
**Ideal internal temperature**: 130-135°F (medium-rare). Rest 5 minutes before serving.
**Common dishes**: rack of lamb (whole rib section roasted), lollipop lamb chops (Frenched rib chops), pan-seared lamb chops.
Loin Chops: The Hidden Gem
**What to look for**: a T-bone shape — a bone in the middle of the chop with meat on both sides. The larger side is the strip loin; the smaller side is the tenderloin (like a miniature T-bone steak in beef). Typically 1-1.5 inches thick.
**Where to find them**: most grocery stores, often underneath rib chops in the lamb case.
**Price range**: $15-25/lb, typically slightly less than rib chops.
**Difference from rib chops**:
- **Shape**: loin chops have a T-bone. Rib chops have a long curved single bone.
- **Meat distribution**: loin chops have meat on two sides of the bone (tenderloin + strip loin). Rib chops have meat on one side.
- **Eye of meat**: loin chops have a larger eye on the strip side. Rib chops have a smaller, more uniform eye.
- **Price**: loin chops are usually 10-20% cheaper than rib chops.
- **Tenderness**: nearly identical — both are tender cuts from the back.
**The value proposition**: loin chops give you 90% of the rib chop eating experience at 80% of the price. If rib chops feel expensive, loin chops are the right substitute.
**How to cook**: same as rib chops — hot and fast. Sear, grill, or broil for 2-3 minutes per side to medium-rare.
Shoulder Chops: The Best Value in Lamb
Shoulder chops come in two main subtypes:
**1. Blade chops**:
- Come from closer to the neck end of the shoulder
- Round-ish shape with a larger piece of bone (often an oval cross-section of the blade/scapula)
- More connective tissue and intramuscular fat
- Stronger lamb flavor
**2. Arm chops**:
- Come from closer to the leg end of the shoulder (the 'arm' or foreshank area)
- Round cross-section with a round bone in the middle (like a mini round steak in beef)
- Slightly leaner than blade chops
- Similar flavor profile
Both are often sold simply as 'shoulder chops' without distinction. They're typically 3/4 to 1 inch thick.
**Price range**: $8-14/lb — the cheapest lamb chop category, roughly 1/3 the price of rib chops.
**The tenderness tradeoff**: shoulder chops are tougher than rib or loin because they come from a working muscle. BUT — the connective tissue and fat make them more flavorful. And with the right cooking method, they can be as delicious as premium cuts at a fraction of the cost.
**How to cook shoulder chops (two approaches)**:
**Approach 1 — Sear hot, cook to medium-rare (130-135°F)**:
Despite conventional wisdom that shoulder cuts need braising, shoulder chops CAN be cooked like loin or rib chops IF you cook them to medium-rare and slice across the grain. The fat in shoulder cuts keeps them juicy. The texture is chewier than loin/rib but the flavor is deeper. Marinate first with lemon, yogurt, garlic, and rosemary to enhance tenderness.
**Approach 2 — Braise slow (the traditional method)**:
Brown the chops on high heat, then simmer in liquid (wine, stock, tomato) at low temperature for 1.5-2 hours. The collagen dissolves into gelatin, creating meltingly tender meat and a rich sauce. Perfect for cold weather meals. Lamb shoulder chops are ideal for Moroccan tagines, Indian curries, and Mediterranean stews.
**Best lamb chop for weeknight cooking**: shoulder chop, seared medium-rare, served with a lemony herb sauce. $10/lb for restaurant-quality lamb when you know what you're doing.
Sirloin Chops: The Middle Ground
**What to look for**: round shape with a round bone in the center (or sometimes boneless cuts). Located between the loin and the leg on the animal. Typically 1-1.5 inches thick.
**Price range**: $12-18/lb, moderate price point.
**Tenderness**: between loin chops (very tender) and shoulder chops (chewier). Sirloin is a working muscle but less than the shoulder, so it's moderately tender.
**How to cook**: similar to loin chops — hot and fast to medium-rare. Works well grilled or pan-seared. Less forgiving than loin because the meat has slightly less intramuscular fat, so don't overcook.
**Availability**: less common in US grocery stores than rib, loin, or shoulder. More common in butcher shops and international markets (Middle Eastern, Mediterranean, and Indian markets often carry sirloin chops).

Common Questions About Buying Lamb Chops
**"How many chops per person?"** Rib and loin: 2-3 chops per person (small and expensive). Shoulder and sirloin: 1-2 chops per person (larger and cheaper). Factor in bone weight — rib and loin have less meat-to-bone ratio than shoulder.
**"What about lamb shanks or stew meat?"** Those aren't chops — shanks are a separate cut from the lower leg, used for braising. Stew meat is cubed meat from various trim cuts. Different category.
**"Is American lamb vs Australian/New Zealand lamb different?"** Yes. American lamb is typically larger (70-90 lb carcass weight), more milk-fed flavor, higher marbling. Australian/NZ lamb is smaller (40-60 lb), grass-fed, stronger flavor, leaner, typically cheaper. Both are good — it's a flavor preference, not a quality judgment.
**"What about goat? Can I use the same chop types?"** Yes — goat is cut very similarly to lamb. The same four chop types exist. Goat flavor is slightly stronger and the meat is leaner. Cook goat slower or marinate longer.
**"How do I know if lamb is fresh?"** Look for bright red color (not brown), moist but not slimy surface, firm texture, and a clean smell. Lamb with a strong gamey smell is past prime freshness. USDA Choice and Prime grades apply to lamb too — look for those shields for higher quality.
