The flavors are simple but deeply satisfying. The baked beans bring sweetness and smoke, the potatoes add heartiness, and the bacon ties it all together with a savory crunch.

Ingredients

2 pounds Yukon Gold or red potatoes, cut into 1-inch cubes
2 cans (28 ounces each) baked beans (original or hickory-smoked)
6 slices thick-cut bacon, cooked crisp and crumbled

Salt, black pepper, and garlic powder are considered free pantry staples and can be added to taste. Optional: 1 small diced onion, 1 teaspoon smoked paprika, or a splash of hot sauce.

Directions

Lightly grease the inside of a 4- to 6-quart slow cooker.
Place the cubed potatoes in the bottom of the slow cooker in an even layer.
Pour the baked beans over the potatoes. Do not stir.
Sprinkle the crumbled bacon over the top. Add optional seasonings if using.
Cover and cook on LOW for 5 to 6 hours, or on HIGH for 2 1/2 to 3 hours, until the potatoes are fork-tender.
Stir gently to combine. If the mixture seems too thick, add a splash of water or broth.
Taste and season with salt, pepper, and garlic powder if needed. Serve hot.

Variations

Smoked Sausage Version: Swap the bacon for 1 pound sliced smoked sausage or kielbasa.
Spicy Baked Bean Casserole: Add diced jalapeños or a pinch of red pepper flakes.
Cheesy Version: Stir in 1 1/2 cups shredded cheddar during the last 15 minutes.
Cowboy Beans Style: Add 1 pound browned ground beef and 1 diced onion.
Different Beans: Use pinto beans, kidney beans, or a mix for a different texture.
Vegetarian: Omit the bacon and add 1 teaspoon smoked paprika for a smoky flavor.

Expert Tips

Cut potatoes evenly so they cook at the same rate.
Do not stir at the beginning. Layering helps the potatoes cook evenly and prevents them from breaking apart.
Use thick-cut bacon for the best texture and flavor.
Watch the moisture. If the casserole looks dry, add a splash of water or broth.
Let it rest before serving so the flavors settle and the sauce thickens slightly.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently in the microwave or in a 350°F oven with a splash of water or broth to loosen. This dish freezes well for up to 3 months. Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions

Can I use canned potatoes? Yes, but add them during the last hour of cooking to prevent mushiness.

Can I make this without bacon? Yes. Use smoked sausage, ham, or omit the meat and add smoked paprika.
Why is my casserole watery? The beans and potatoes release liquid as they cook. Leave the lid slightly ajar for the last 20 minutes.
