Why You'll Love This Recipe

• Chuck steak breaks down into incredibly tender, melt-in-your-mouth pieces after hours in the slow cooker.
• Using full-fat coconut milk creates a naturally creamy, luscious sauce without needing dairy.
• A hands-off recipe where the slow cooker does all the heavy lifting for you.
• Balances savory, sweet, and tangy flavors thanks to palm sugar, fish sauce, and tamarind paste.

Ingredients You'll Need (and Why)

Chuck steak: This cut has plenty of intramuscular fat and connective tissue, which breaks down over long, slow cooking to yield tender, fork-shreddable meat.

Massaman curry paste: Unlike fiery green or red curry pastes, Massaman paste relies on warm spices like cumin and coriander, offering a milder, deeply savory flavor profile.

Full-fat coconut milk: Full-fat canned coconut milk provides the necessary fat content to keep the sauce rich and prevent it from curdling during a long cook time.

Tamarind paste: Brings an essential fruity tartness that cuts through the richness of the coconut milk and balances the sweetness of the palm sugar.

Cinnamon stick & star anise: These whole warm spices infuse the liquid as it cooks, giving authentic depth to the classic Massaman aroma and flavor.

How to Make It

Creating the Flavor Base

Whisking the curry paste directly into the initial liquids ensures it dissolves evenly without leaving clumps. Combining the fish sauce, tamarind, and sugar right at the start allows the complex sweet-salty-sour profile to infuse every ingredient as it cooks.

Layering and Slow Cooking

Submerging the beef and potatoes into the seasoned liquid while holding back some coconut milk creates a rich gradient of flavor. As the slow cooker runs on low heat, the collagen in the chuck steak melts away, thickening the curry naturally.

Success Tips

• Cut your chuck steak into uniform 1.5-inch chunks so they cook evenly throughout the long braising time.
• Use baby yellow potatoes as they hold their shape much better during long, slow cooking compared to larger starchy potatoes.
• Make sure to whisk the curry paste thoroughly with the liquid before adding the solids to avoid pockets of unblended paste.
• Do not skip the whole spices (cinnamon and star anise)—they are key to authentic Massaman flavor.

Variations

• Swap out the chuck steak for boneless, skinless chicken thighs if you prefer poultry over beef.

Storage & Make-Ahead

Fridge: Store leftovers in an airtight container in the refrigerator for up to 3 to 4 days.

Freezer: Freeze in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating.

FAQ

Can I use chicken instead of beef?

Yes, boneless chicken thighs work wonderfully in this recipe, though you will want to reduce the cooking time since chicken cooks much faster than chuck steak.

Why do I need to hold back half the coconut milk?

Pouring half the coconut milk into the base and the rest over the top helps create a layered, rich sauce texture as everything slowly simmers together.

Can I make this on the stovetop instead?

You can simmer this in a heavy-bottomed Dutch oven over low heat for about 2.5 to 3 hours until the beef is tender, stirring occasionally.
