Ingredients

For the Protein Base:

• 1 pound lean ground beef
• 4 ounces bacon, chopped
• ½ cup chopped onion

For the Bean Mixture:

• 1 (16 ounce) can baked beans with pork
• 1 (15 ounce) can kidney beans, undrained
• 1 (15 ounce) can butter beans, undrained

For the Sauce:

• ¾ cup packed brown sugar
• ½ cup ketchup
• 1 tablespoon dry mustard
• 2 teaspoons white vinegar
• Salt and freshly ground black pepper to taste

Steps

1. Preheat your oven to 350°F (175°C). Position the rack in the center of the oven for even cooking, and lightly grease a 9×13-inch baking dish to prevent sticking.
2. Heat a large skillet over medium heat until hot but not smoking. Add the chopped bacon first and cook for 2-3 minutes until it starts rendering fat, then add the ground beef and chopped onion. Cook and stir continuously for 5-7 minutes until the beef is completely browned and crumbly with no pink remaining. The bacon should be crispy and the onion translucent. Drain off excess fat using a slotted spoon or by carefully tilting the pan.
3. In a large mixing bowl, combine all three types of beans with their liquids – the baked beans with pork, kidney beans, and butter beans. Don’t drain the kidney and butter beans as their liquid adds flavor and helps create the perfect sauce consistency. Stir gently to avoid mashing the beans.
4. Add the brown sugar, ketchup, dry mustard, and white vinegar to the bean mixture. Stir thoroughly until the brown sugar is completely dissolved and the sauce is evenly distributed. The mixture should have a rich, glossy appearance and smell sweet and tangy.
5. Fold in the cooked beef, bacon, and onion mixture, stirring gently but thoroughly to distribute the meat evenly throughout. Season with salt and freshly ground black pepper to taste – start with ½ teaspoon salt and ¼ teaspoon pepper, then adjust as needed.
6. Transfer the entire mixture to your prepared 9×13-inch baking dish, spreading it evenly with a spatula. The casserole should be about 2 inches deep in the dish.
7. Bake in the preheated oven for 30-40 minutes until the top is golden brown and the sauce is bubbling around the edges. The internal temperature should reach 165°F (74°C) when tested with an instant-read thermometer. If the top browns too quickly, tent loosely with foil for the last 10 minutes of baking.

Smart Swaps

• Turkey bacon instead of regular bacon – reduces fat by 40% while keeping that smoky flavor
• Ground turkey (93/7 lean) instead of beef – cuts calories and saturated fat significantly
• Sugar-free ketchup and brown sugar substitute – reduces sugar content by 75% per serving
• Low-sodium beans – helps control salt intake without sacrificing taste

Make It Diabetes-Friendly

Replace the ¾ cup brown sugar with ⅓ cup granulated erythritol or stevia blend (reduces carbs by 35g per serving). Use sugar-free ketchup to cut another 8g carbs per serving. Choose no-sugar-added baked beans to reduce total carbs from 45g to 28g per serving. The glycemic impact drops significantly with these swaps – pair with a side salad or steamed vegetables to further slow glucose absorption. Consider serving ¾ cup portions instead of full cups to keep carbs under 25g per serving, making it much more blood sugar friendly.

Pro Tips

• Let the casserole rest for 10 minutes after baking – the sauce thickens perfectly and makes serving cleaner
• Make it a day ahead – flavors meld beautifully overnight in the fridge, just add 5 extra minutes to reheat time
• Freeze individual portions in meal prep containers for up to 3 months – perfect grab-and-go lunches
