Oven Baked Calico Beans Casserole

Calico beans casserole is a hearty oven-baked dish made with ground beef, bacon, two kinds of beans, and a sweet barbecue sauce. A little diced onion and Worcestershire sauce give the sauce extra savory flavor, while the oven brings everything together into a bubbly casserole that works as a side dish or an easy supper.

This is the kind of recipe that fits right in at a backyard cookout, potluck, or family dinner. Most of the hands-on work happens in one skillet, and once the beans are in the baking dish, the oven takes care of the rest.

The pork and beans bring their own sauce, kidney beans add a firmer bite, and the ground beef makes each serving filling. Crisp bacon adds smoky bits throughout, while barbecue sauce ties everything together with a familiar sweet-and-tangy taste.

Why You’ll Love This Recipe:

You get a filling dish from everyday ingredients, and there is no need to soak or cook dried beans. The canned beans are ready to use, so the main prep is cooking the bacon, onion, and beef before stirring everything together. It is also easy to make ahead when you have guests coming.
The sauce turns thick and bubbly around the edges, and the beans stay tender without falling apart. It can sit beside burgers and grilled chicken at a cookout, but it is hearty enough to serve in a bowl with cornbread for a casual dinner. Leftovers reheat well for another meal.

Ingredients You’ll Need:

You’ll need ground beef, bacon, a small yellow onion, pork and beans, kidney beans, barbecue sauce, and Worcestershire sauce. Use regular canned pork and beans and keep their sauce; drain the kidney beans so they do not add extra liquid.

Ground Beef

One pound of ground beef makes the casserole filling enough to serve as more than just a side. Use 85% or 90% lean beef if you want less grease to drain from the skillet before mixing.

Bacon

Cook the bacon until crisp, then crumble it into bite-size pieces. Crisp bacon holds its shape better in the casserole and gives the soft beans little smoky bites.

Pork and Kidney Beans

Pork and beans provide the saucy base, so do not drain them. Kidney beans should be drained and rinsed; this removes the canning liquid and helps keep the casserole from becoming too loose.

Barbecue and Worcestershire Sauces

Choose a barbecue sauce you already enjoy, whether it is smoky, sweet, or a little tangy. Worcestershire sauce adds a savory note, so you do not need to add extra seasoning to make the sauce taste fuller.

How to Make Calico Beans Casserole:

Have a 3-quart oven-safe casserole dish ready, and heat the oven before you start cooking.

1. Heat the Oven and Prepare the Dish

Preheat the oven to 350°F. Lightly grease a 3-quart casserole dish and set it aside while you cook the bacon and beef.

2. Cook the Bacon

Cook the bacon in a large skillet over medium heat until crisp. Transfer it to a paper towel-lined plate, let it cool slightly, and crumble or chop it into small pieces.

3. Soften the Onion and Brown the Beef

Leave about 1 tablespoon of bacon drippings in the skillet and add the diced onion. Cook for 3–4 minutes, stirring, until softened. Add the ground beef and cook, breaking it up, until no pink remains; drain excess grease.

4. Stir the Bean Mixture Together

In a large bowl, combine the pork and beans with their sauce, drained kidney beans, barbecue sauce, Worcestershire sauce, cooked beef and onion, and crumbled bacon. Stir until the beef and bacon are spread throughout the beans.

5. Bake Until Bubbly

Spoon the mixture into the prepared casserole dish and spread it into an even layer. Bake uncovered for 45–55 minutes, until hot in the center, bubbling around the edges, and slightly thickened. Let it rest for 5 minutes before serving.

Storage, Freezing, and Reheating

Store cooled leftovers in an airtight container in the refrigerator for 3–4 days. Refrigerate within 2 hours of baking.

To freeze, cool the casserole and pack it in freezer-safe containers for up to 2–3 months. Thaw overnight in the refrigerator for more even reheating.

Reheat individual portions in the microwave to 165°F, stirring if needed. For a larger amount, cover an oven-safe dish and warm at 325°F until the center reaches 165°F; add a spoonful of water if the beans look dry.

What to Serve with Calico Beans Casserole

Grilled Burgers or Hot Dogs

The sweet barbecue sauce and smoky bacon fit right in beside burgers, hot dogs, or grilled sausages.

Cornbread

A warm square of cornbread is handy for scooping up the extra sauce and makes this a filling meat-and-beans dinner.

Coleslaw

Cool, crunchy coleslaw gives the plate a fresh contrast to the soft beans and rich beef.

Grilled Chicken

Serve a spoonful alongside grilled chicken when you want a simple cookout plate with a hearty side.

Frequently Asked Questions

Can I make calico beans casserole ahead of time?

Yes. Cook the bacon, onion, and beef, then mix the casserole and transfer it to the baking dish. Cover and refrigerate for up to 24 hours; bake until hot and bubbling, allowing extra time if it goes into the oven cold.

Can I use a different kind of bean?

You can swap the kidney beans for drained butter beans, navy beans, or lima beans. The texture will change a little, but the casserole will still have its sweet barbecue sauce and hearty bean base.

How do I keep the casserole from getting watery?

Drain the kidney beans and excess grease from the beef, but keep the sauce from the pork and beans. Bake uncovered so extra moisture can cook off, and give it a few minutes to rest before serving.

Can I serve this as a main dish?

Yes. The beef, bacon, and beans make it filling enough for a main dish. Serve it with a green salad, cornbread, or steamed vegetables.
