Slow Cooker Japanese Curry Pork

This slow cooker Japanese curry pork is the ultimate set-and-forget dinner. Just layer pork, potatoes, carrots, and curry roux in the crockpot, pour in broth, and let it simmer all day.

The result is fork-tender meat and vegetables in a rich, savory sauce that's deeply satisfying. Perfect for busy weeknights, this recipe turns simple ingredients into a comforting meal that tastes like it took hours of attention—but really, the slow cooker does all the work.

Japanese curry is a beloved comfort food, and this slow cooker version makes it even easier. The pork loin becomes incredibly tender as it cooks low and slow, while the potatoes and carrots soak up the flavorful curry sauce.

The curry roux—a block of seasoned flour and fat—melts into the broth, creating a thick, glossy sauce that clings to every bite. With just five ingredients and a few minutes of prep, you can have a hearty, warming dinner waiting for you at the end of the day. Serve it over steamed rice for a complete meal that the whole family will love.

Ingredients

Why this recipe works

The slow cooker does the heavy lifting here. Cooking the pork on low heat for an extended time breaks down the connective tissue, turning even lean pork loin into tender, fork-friendly pieces. The gentle, moist heat also allows the potatoes and carrots to soften evenly without falling apart, so every spoonful has a nice texture contrast.

The curry roux is the secret to the sauce. As it melts into the broth, it releases a blend of spices—turmeric, cumin, coriander, and more—and thickens the liquid into a velvety sauce. Because the roux is added at the beginning, it has time to fully dissolve and meld with the other ingredients, creating a cohesive, deeply flavored curry that's far more complex than the sum of its parts.

Notes and substitutions

Pork loin is a great choice because it's lean but becomes tender with long, slow cooking. If you prefer a richer flavor, pork shoulder works wonderfully too—just trim excess fat.

For the vegetables, Yukon Gold or russet potatoes hold up well, and regular carrots are perfect. The Japanese curry roux is sold in blocks at most supermarkets; look for brands like S&B or Vermont, but any brand will work.

A 6-quart slow cooker is ideal for this recipe, but a 4-quart will also work if you adjust the quantities slightly. If you don't have a slow cooker, you can simmer everything in a Dutch oven on the stovetop for about 1 1/2 hours, or until the pork is tender.

For a thicker sauce, whisk the roux into a little hot broth before adding it to the slow cooker. For a thinner sauce, add a bit more broth at the end.

• pork loin: pork shoulder or boneless chicken thighs (adjust cooking time as needed)
