The 5-Star Ingredients

This recipe proves that you don’t need a long ingredient list to create something delicious. Here’s what you’ll need:

Ground beef – 1 pound. Ground beef adds savory, hearty flavor and protein. As it cooks, it becomes tender and blends perfectly with the beans and sauce.

Baked beans – 2 cans (28 ounces each). Baked beans are the hearty, sweet base of this dish. They provide fiber, protein, and a rich, tomatoey flavor that pairs perfectly with the beef and barbecue sauce.

Onion – 1 medium, finely chopped. Onion adds sweetness and savory depth as it cooks. It becomes soft and tender, adding flavor to every bite.

Barbecue sauce – ½ cup. Barbecue sauce adds a sweet, smoky, tangy flavor that elevates the dish and ties all the ingredients together.

Yellow mustard – 1 tablespoon. Mustard adds a tangy, slightly sharp note that balances the sweetness of the barbecue sauce and baked beans.

That’s it. Five ingredients. No complicated steps. Just honest, delicious ingredients that come together beautifully.

Step-by-Step Instructions (The Short Version)

Lightly grease the inside of your slow cooker if desired for easier cleanup. Add the raw ground beef to the bottom of the slow cooker and break it up slightly with a spoon.
Scatter the chopped onion over the beef. Pour the baked beans over the top, then add the barbecue sauce and yellow mustard.
Stir everything together well so the beef is evenly distributed through the beans and sauce.
Cover and cook on LOW for 5 to 6 hours or on HIGH for 3 to 4 hours, stirring once or twice if convenient, until the beef is fully cooked and the flavors have melded.
Stir well before serving and serve hot with your choice of sides.

How to Serve It Like a Pro

This dish is delicious on its own, but a few simple additions make it even better:

With cornbread – The perfect Southern pairing.
With crusty bread – For soaking up every last bit of sauce.
Over rice – A simple and satisfying bed for the beef and beans.
With a side salad – A crisp green salad cuts through the sweetness.
With hot dogs – Serve alongside grilled hot dogs for a classic cookout meal.
With coleslaw – Adds crunch and tanginess.
With pickles – The tanginess of pickles balances the sweetness.
With a sprinkle of fresh parsley – Adds brightness and color.
