Slow Cooker
I used a 4.5-quart slow cooker, which easily makes 5-8 servings with rice. I cook it low and slow, checking the beef around 7 hours in. If tender, I add green beans, cook for 15-20 minutes, and serve.

Ingredients for Massaman Curry
- Beef – Chuck roast is the best choice because it has just the right balance of marbling and leanness for a slow-cooked curry. Avoid pre-cut stew meat, as it can sometimes have too much fat. If you get a large roast, trim it yourself and freeze any extra for future recipes.
- Red curry paste – Different brands have varying spice levels, so start with 2-3 tablespoons and adjust based on your preference. If you love extra heat, you can always add more at the end.
- Cinnamon – The cinnamon stick infuses the curry with warmth, but if you're sensitive to the flavor, use only ½ teaspoon of ground cinnamon or skip it entirely. You’ll still get a rich blend of spices from the curry paste.
- Kaffir lime leaves – These are optional but add a lovely citrusy aroma. If you can find them, toss them in with the broth and spices for a more authentic flavor.
- Beef broth – Start with 1 cup and add up to ½ cup more if needed for a thinner curry. This is a matter of preference, so adjust based on how thick you like it.
- Coconut milk – Full-fat coconut milk gives the curry a creamier, more luxurious texture. If you want a thicker consistency, reduce the amount of broth and let the coconut milk shine.

How To Make Massaman Beef Curry
Prepare your meat by trimming the excess fat off and cutting the beef into 1 ½ inch cubes. Season the meat with salt and pepper.
Heat up vegetable oil in a large heavy bottom pan over medium-high heat. Sear the beef chunks until well golden brown (about 4 minutes on both sides is enough).
Don’t overcrowd the pan, you’ll need to do this in batches, carefully cleaning the surface of the pan with a paper towel if necessary and adding more oil before the next batch.
Don’t change the heat temperature and don’t overcook the beef. Transfer to 4.5-quart slow cooker.
Add chopped potatoes, carrots.
In the same pan (cleaned slightly with a paper towel), saute onion until softened and add red curry paste and garlic. Saute 2 minutes more on medium-low. Transfer to slow cooker.
Add spices, broth, lime juice, coconut milk, cinnamon stick, a handful of cilantro leaves to the slow cooker. If using kaffir leaves, add them now.
Cook on LOW for 8 hours or HIGH 4 hours. After that taste for seasoning and add more salt/pepper if necessary.
Top with green beans and cook on HIGH for another 15 minutes or LOW for 30 minutes. Taste for seasoning again.
Garnish Massaman Beef Curry with plenty of fresh herbs such as cilantro, mint, parsley, lime wedges, more crushed red chili flakes, peanuts. Serve as it is with bread, grains, rice.
Massaman paste vs Red curry paste
>Massaman paste is milder and sweeter, with Indian-inspired spices like cinnamon, cardamom, and peanuts, giving it a rich, earthy flavor.
>Red curry paste is spicier and tangier, made with ingredients like dried red chilies, lemongrass, and shrimp paste for a more vibrant, pungent taste.
Curry Tips
- Thickening the curry. If you want a thicker Massaman curry, use less broth and increase the coconut milk. Another option is to mix 1-2 tablespoons of cornstarch with water and stir it into the slow cooker during the last 15 minutes of cooking.
- If the curry is too thin, let it simmer uncovered for a bit longer, or mix in a cornstarch slurry (1-2 tablespoons cornstarch + water) to thicken it up.
- Searing the beef. Don’t skip this step! Browning the meat first locks in flavor and gives the curry a deeper, richer taste. Work in batches so you don’t overcrowd the pan.
- Layering flavors. After sautéing the onions, make sure to toast the curry paste in the pan for 1-2 minutes before adding it to the slow cooker. This helps release the oils and intensifies the flavors.
- Serving suggestion. This curry is delicious on its own but even better with rice, naan, or crusty bread to soak up the sauce. Garnish with fresh cilantro, roasted peanuts, and a squeeze of lime for a bright, flavorful finish.
Freezing and Storing
- To Store. Let it cool completely, place the curry in airtight containers, refrigerate and consume within 2-3 days. Or freeze for 2-3 months.
- After thawing, however, the texture will change slightly which is very common with cream sauce, ‘’milk’’ based recipes. To restore its first look (as much as we can after thawing), and make it more creamy stir in fresh coconut milk or heavy cream when reheating.

NOTES
- Beef: Any chuck roast or round cut works great for Massaman curry. I buy meat from my local butcher to ensure it’s fresh and just right for the recipe. Avoid pre-cut stew meat as it often has too much fat. If you get a big chuck roast, cut what you need for this curry and freeze the rest.
- Red curry paste: Different brands can vary in spice, so start with 2-3 tablespoons. Adjust to your preference.
- Cinnamon: If you don’t like strong cinnamon flavor, use just ½ teaspoon or skip it. The cinnamon stick will blend into the curry, adding a subtle flavor common in Indian dishes.
- Additions: Kaffir leaves add a nice lime flavor if you have them on hand.
- Beef broth: Use 1 cup beef broth, but add an extra ½ cup for a thinner curry, based on your preference. Full-fat coconut milk adds a rich, creamy texture.
- Slow cooker: A 4.5-quart slow cooker is perfect for 5-6 portions, or up to 7-8 with rice. After 7 hours, check the beef for tenderness, then add green beans and cook for 15-20 minutes more.
- What beef is best for curry? The best beef for curry is one that’s tender and cooks well in stews or pot roasts. Chuck roast is ideal since it’s lean but well-marbled, making it easy to get tender beef chunks.
- How to thicken your curry: To thicken the curry, use less broth and more coconut milk. Alternatively, mix 1-2 tablespoons of cornstarch with water, then stir it into the curry towards the end. Cook on high for 15 minutes to thicken.

Delicious! Made a lot so I had lots of leftovers. The beef cubes were falling-apart-tender, and I cooked everything on Low for 6 3/4 hours. I used an entire pound bag of frozen green beans, more than the 1/2 cup called for. I adjusted the seasonings thusly: 3 T of red curry paste, 1 T low-sodium soy sauce, and 1 t of nutmeg. I couldn't find any Kaffir leaves. I served it over brown jasmine rice. This one-pot meal was well-seasoned and just-spicy enough. I took a chance making this because boneless beef chuck roasts are not cheap, and I am so glad I did! Definitely a keeper! http://www.what-marsha-eats.tumblr.com

Marsha! Thank you so much for sharing this! Delicious wasn't it?! I love kaffir leaves but true so hard to find unless in a specialized store. I find that adding more lime juice helps. Thank you so much for your positive feedback!

Looks amazing! Quick question: what if you have the massaman paste? Could I just use that instead of the red curry? If so, what would I add or do differently?
Julia | The Yummy Bowl
hi Jess, thank you so much! I really love the flavors in red curry paste, the red chilis dominate here quite a bit, which is more Thai-style. Massaman (authentic) has also red chilis, but less and has stronger flavors of cinnamon and cardamom, which are both closer to Indian cuisine. I am not sure but if using Massaman, I'd add some extra red chilis to the mix.
