Ingredients You’ll Need
The classic version includes three types of beans combined with a sweet and savory sauce. Here’s a basic ingredient list:
- 1 can (15 oz) kidney beans – drained and rinsed
- 1 can (15 oz) green beans – drained
- 1 can (15 oz) baked beans – undrained
- ½ cup chopped onion
- ½ cup chopped green bell pepper
- 2 cloves garlic, minced
- ½ cup ketchup
- ¼ cup brown sugar
- 1 tbsp apple cider vinegar
- 1 tbsp mustard (yellow or Dijon)
- 1 tsp Worcestershire sauce (optional)
- 1 tbsp olive oil or butter
- Salt & pepper to taste
Optional: If you prefer a meatier casserole, you can add ½ pound of browned ground beef or bacon bits.
Step-by-Step Preparation
Step 1: Preheat the Oven
Set your oven to 350°F (175°C) to get it ready while you prepare the casserole.
Step 2: Sauté Vegetables
In a skillet, heat olive oil (or butter). Add onions, green peppers, and garlic. Sauté for 3–4 minutes until fragrant and slightly golden.
Step 3: Combine the Beans
In a large mixing bowl, combine kidney beans, green beans, and baked beans. Stir gently to mix.
Step 4: Prepare the Sauce
Add ketchup, brown sugar, vinegar, mustard, Worcestershire sauce, salt, and pepper. Stir until smooth and well-blended.
Step 5: Mix Everything Together
Combine the sautéed vegetables, beans, and sauce in the same bowl. If adding ground beef or bacon, mix that in as well.
Step 6: Bake the Casserole
Transfer everything into a greased casserole dish. Bake uncovered for 35–40 minutes, until bubbly and slightly caramelized on top.
Step 7: Serve Hot
Once done, let it cool for about 5 minutes before serving. This resting time helps the flavors deepen.
Tips for the Best Casserole
- Balance Sweet and Savory – Adjust sugar and vinegar based on taste preference. Some like it tangier; others prefer a sweeter flavor.
- Texture Matters – Keep the beans whole; don’t over-mash them.

- Make it Ahead – Prepare the casserole, refrigerate overnight, and bake the next day.
- Slow Cooker Method – You can also cook this casserole on low heat in a slow cooker for 4–5 hours.
