My frugal grandmother relied on this exact dinner when money was tight. Just 3 ingredients for a hearty comforting meal that will feed the whole house tonight.

When I was a girl growing up in the rural Midwest, my grandmother had a few suppers she could count on when money was tight and mouths were many. This slow cooker 3-ingredient franks and beans was one of them. A big bubbling pot of soft, molasses-glossed beans and plump hot dog slices could stretch just a couple of dollars into a hearty, comforting meal that filled the whole house with a cozy, smoky-sweet smell. It’s as humble as can be, but it sticks to your ribs, uses only three pantry-friendly ingredients, and quietly proves that simple food can still feel like a warm hug at the end of a long day.

Ladle these franks and beans into bowls and serve with slices of soft white bread, cornbread, or buttered toast for dipping into that rich, brown sauce. A simple side of coleslaw, carrot sticks, or sliced cucumbers adds a fresh crunch alongside all that sweetness and smoke. If you want to stretch it even further, spoon the mixture over hot cooked rice or boiled potatoes. Around here, we set the slow cooker right on the counter and let everyone help themselves, with mustard and a little hot sauce on the side for those who like a sharper bite.

Servings: 6-8

2 (28-ounce) cans baked beans in rich molasses or brown sugar sauce

Lightly grease the inside of a 4- to 6-quart slow cooker with a bit of oil or nonstick spray to make cleanup easier.

Pour the baked beans, including all of their thick sauce, into the slow cooker. Stir gently to break up any clumps and spread them into an even layer.

Add the sliced hot dogs on top of the beans. Pour the ketchup over everything.

Stir well until the hot dog slices are evenly distributed and the ketchup is mixed into the bean sauce. The mixture should look thick and glossy, with the hot dogs nestled throughout.

Cover the slow cooker with the lid. Cook on LOW for 4 to 6 hours, or on HIGH for 2 to 3 hours, until the beans are very soft, the hot dogs are plump, and the sauce is bubbling and slightly thickened with a dark molasses shine.

Taste and adjust if you like: if you prefer it sweeter, you can stir in a spoonful of extra ketchup; if you like more tang, add a small splash of vinegar right at the end. Stir well to combine.

Turn the slow cooker to WARM and let the franks and beans sit for 10 to 15 minutes before serving. This resting time helps the sauce thicken a bit more and lets the flavors settle together.

Serve hot, straight from the slow cooker, making sure each scoop has plenty of beans and hot dog slices in that rich, bubbling brown sauce.

To keep this true to my grandmother’s frugal style, the base recipe uses just three simple ingredients, but you can still make it your own. For extra smokiness without adding more ingredients, choose baked beans labeled “hickory,” “smokehouse,” or “maple and bacon.” If you need to stretch the meal even further, add an extra can of baked beans and a splash of water; the flavor will still be comforting and it will feed more people. For a bit of bite, set yellow mustard, prepared horseradish, or hot sauce on the table so each person can season their own bowl without changing the core recipe. If you’re watching sodium, look for reduced-sodium baked beans and hot dogs, and taste before adding any extra condiments. Food safety tips: Keep the hot dogs refrigerated until you’re ready to slice and add them to the slow cooker. Do not leave the cooked franks and beans at room temperature for more than 2 hours (or 1 hour if your kitchen is very warm); switch the slow cooker to WARM and keep it covered if people are serving themselves over time. Refrigerate leftovers in shallow containers within 2 hours and use within 3 to 4 days, reheating until the mixture is piping hot and bubbling before serving. If the sauce thickens too much when reheating, stir in a spoonful or two of water to loosen it back up.
