Ingredients

  

• 1 tablespoon olive oil
• 1 large yellow onion, diced
• 1 red bell pepper, diced
• 3 cloves garlic, minced
• 1.5 pounds (680 g) lean ground beef (90% lean or higher)
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 2 teaspoons ground cumin
• 1.5 teaspoons smoked paprika
• 1 teaspoon dried oregano
• 1/2 teaspoon chili powder or chipotle powder (optional for heat)
• 1 can (15 oz/425 g) black beans, drained and rinsed
• 1 can (15 oz/425 g) kidney beans, drained and rinsed
• 1 can (14.5 oz/410 g) diced tomatoes, with juices
• 1 cup tomato sauce or crushed tomatoes
• 1 cup frozen or canned corn, drained (optional)
• 1/2 cup low-sodium beef broth or water, as needed
• 1/2 cup Greek yogurt or light sour cream
• 1 cup shredded cheddar or Monterey Jack cheese (reduced-fat works well)
• 2 tablespoons chopped fresh cilantro or parsley (optional)
• Juice of 1/2 lime (optional)

Method

 

1. Preheat and prep: Heat your oven to 375°F (190°C). Lightly grease a 9x13-inch casserole dish.
2. Sauté aromatics: Warm the olive oil in a large skillet over medium heat. Add the onion and bell pepper. Cook 5–6 minutes until softened and lightly golden. Stir in garlic and cook 30 seconds until fragrant.
3. Brown the beef: Add the ground beef to the skillet. Season with salt and black pepper. Cook, breaking it up with a spoon, until no longer pink and lightly browned, about 6–8 minutes. Drain excess fat if needed.
4. Season it up: Sprinkle in cumin, smoked paprika, oregano, and chili powder if using. Stir and cook 1 minute to bloom the spices.
5. Add beans and tomatoes: Stir in black beans, kidney beans, diced tomatoes with juices, tomato sauce, and corn. If the mixture looks very thick, add up to 1/2 cup broth or water. Simmer 5 minutes to meld flavors. Taste and adjust salt.
6. Finish the base: Off the heat, stir in Greek yogurt for creaminess. Add lime juice if you like a hint of brightness.
7. Assemble: Transfer the mixture to the casserole dish. Sprinkle cheese evenly over the top.
8. Bake: Place on the middle rack and bake 18–22 minutes, until bubbling around the edges and the cheese is melted and lightly golden.
9. Rest and garnish: Let it sit 5–10 minutes so it sets slightly. Sprinkle with chopped cilantro or parsley before serving.
10. Serve: Enjoy as-is, or add toppings like sliced green onions, diced avocado, or a spoon of salsa. It pairs well with a simple side salad or roasted veggies.

Health Benefits

• High-quality protein: Lean beef provides complete protein for muscle repair and satiety.

  Beans add plant protein for a balanced profile.

• Fiber for fullness: Beans bring soluble and insoluble fiber, which supports digestion and helps manage appetite.
• Micronutrient boost: Beef offers iron, zinc, and B vitamins. Tomatoes and peppers add vitamin C, lycopene, and antioxidants.
• Smart fats and carbs: Olive oil, moderate cheese, and slow-digesting carbs from beans keep energy steady and cravings in check.

Pitfalls to Watch Out For

• Over-salting: Canned beans and tomatoes vary in sodium. Taste before adding extra salt, and choose low-sodium options when possible.
• Too much liquid: Some brands of tomatoes are juicier.

  If your mixture is very soupy, simmer a few extra minutes before baking.

• Greasy texture: If using beef with higher fat, drain well after browning or blot with a paper towel to keep the casserole light.
• Overbaking: The filling is already cooked. Bake just until bubbling and the cheese is melted to avoid a dry texture.

Recipe Variations

• Veggie-loaded: Stir in diced zucchini, mushrooms, or spinach during the sauté step for extra volume and nutrients.
• Tex-Mex style: Add 1 can diced green chiles and swap cheddar for pepper jack. Top with crushed baked tortilla strips right before serving.
• Sweet potato boost: Fold in 1–2 cups small-diced, pre-roasted sweet potato for a hearty, slightly sweet twist.
• Lower dairy: Skip the yogurt and reduce cheese to 1/2 cup.

  It will still be rich and flavorful.

• Turkey or bison swap: Replace beef with lean ground turkey or bison for a lighter or gamey alternative.
• No corn version: Omit corn if you’re keeping carbs tighter. Add extra bell pepper or mushrooms instead.

FAQ

Can I make this casserole gluten-free?

Yes. The base recipe is naturally gluten-free if you confirm your spices, broth, and canned goods are certified gluten-free.

Serve with a simple salad or gluten-free grains if you want extra sides.

How can I make it spicier?

Add 1 finely chopped jalapeño with the onion, bump up the chili powder, or swirl in a teaspoon of chipotle in adobo. A dash of hot sauce at the table also works well.

What cheese melts best for this?

Cheddar, Monterey Jack, or a Mexican blend all melt smoothly. For a bit more stretch, mix in a little mozzarella with cheddar.

Can I use dried beans instead of canned?

Absolutely.

Cook them in advance until tender, then measure about 1.5 cups cooked per 15-ounce can. Make sure they’re well-drained to avoid excess moisture.

How do I lighten the calories without losing protein?

Use extra-lean beef or ground turkey, reduce cheese by half, and keep the Greek yogurt. You’ll keep the protein high while trimming fat and calories.

What can I serve with it?

A crisp green salad, steamed broccoli, or roasted green beans all balance the richness.

If you want carbs, brown rice or quinoa is a natural match.

Can I make it in a slow cooker?

Yes. Brown the beef and sauté the aromatics first, then add everything except the cheese and yogurt to the slow cooker. Cook on low 4–5 hours.

Stir in yogurt at the end, top with cheese, cover until melted, and serve.

How do I prevent a watery casserole?

Drain beans well, don’t skip the brief simmer, and bake uncovered. If your tomatoes are very juicy, reduce the broth or skip it entirely.
