Cheesy Baked Mexican Beef and Beans

One-Pan, Family Favorite

This cheesy beef-and-bean bake is all comfort, no fuss. Brown the beef once, stir everything together, cover with foil, and let the oven do the work. Finish with a blanket of melty cheese and bring it to the table with lime and tortilla chips.

What Makes This Recipe So Good

• Big flavor, tiny effort. Taco-seasoned ground beef, black beans, corn, salsa, and lots of cheese bake into one scoopable, cozy casserole.
• Real dump-and-bake energy. Brown the beef, then everything else gets mixed right in the baking dish—no extra bowls to wash.
• Works for weeknights or potlucks. Covered bake = hands-off time. Add the cheese at the end for a bubbly, golden finish.
• Flexible and family-friendly. Choose mild or medium salsa, black or pinto beans, cheddar or Monterey Jack. Add heat at the table.

Ingredients

For the Casserole

• 1 tablespoon olive oil (only if beef is very lean)
• 1½ pounds ground beef (80–90% lean)
• 1 medium yellow onion, finely diced
• 3 cloves garlic, minced
• 1 (15-ounce) can black beans, drained and rinsed (or pinto beans)
• 1 cup frozen corn kernels (no need to thaw)
• 1 (16-ounce) jar salsa (mild, medium, or hot)
• ½ cup beef broth or water
• 2 tablespoons taco seasoning (store-bought or homemade)
• 1 teaspoon ground cumin
• Pinch ground cinnamon (optional, for warmth)
• 1 cup shredded Mexican-blend cheese
• White parts from 3 sliced green onions

To Finish

• 1 cup shredded Mexican-blend cheese

Serving Suggestions (All Optional)

• Green parts from 3 sliced green onions
• Chopped fresh cilantro
• Sliced avocado
• Mexican crema or sour cream
• Lime wedges
• Warm tortillas or tortilla chips

Instructions

1. Preheat oven to 375°F. Lightly grease a 9×13-inch casserole dish.
2. Brown the beef. Heat a large skillet over medium-high. Add beef (and olive oil if lean). Cook 5–7 minutes, breaking into crumbles, until well browned with no pink. Drain excess fat, leaving about 1 tablespoon.
3. Sauté aromatics. Add onion and a pinch of salt; cook 3–4 minutes until translucent. Stir in garlic 30 seconds until fragrant.
4. Season. Stir in taco seasoning, cumin, and a tiny pinch of cinnamon. Cook 30–60 seconds to bloom spices.
5. Dump & stir in the dish. In the casserole dish, combine the cooked beef mixture, black beans, corn, salsa, broth, white parts of green onions, and 1 cup cheese. Stir until evenly distributed. Mixture should be saucy but not soupy.
6. Cover & bake. Cover the dish tightly with foil and bake 25 minutes. Look for bubbles around the edges when you peek.
7. Uncover & cheese. Remove foil. Sprinkle remaining 1 cup cheese evenly on top. Return to oven uncovered and bake 10–15 minutes, until cheese is melted with light golden spots.
8. Rest & serve. Let casserole rest 10 minutes to set. Garnish with green onion tops, cilantro, avocado, and a drizzle of crema. Serve warm with lime and tortillas or chips.

Chef’s Tips

• The covered bake keeps everything creamy and melds flavors—don’t skip the foil.
• Salsa and taco seasoning vary in saltiness. Taste after baking and add a pinch of salt or a squeeze of lime if needed.
• Want it spicier? Use medium/hot salsa or add chopped pickled jalapeños on top after baking.
• If the casserole looks a little loose when it comes out, that’s fine—it firms up as it rests for 10 minutes.

Variations

• Turkey or Chicken: Swap beef for ground turkey/chicken; add 1 tablespoon oil and an extra pinch of cumin.
• Bean Blend: Use half black beans, half pinto for a creamier scoop.
• Enchilada-Style: Replace salsa with red enchilada sauce; add ½ teaspoon ground coriander.
• Chipotle Smoky: Stir in 1 finely chopped chipotle in adobo plus 1 teaspoon adobo sauce.
• Street-Corn Finish: After baking, dust with Tajín, add crumbled cotija, and drizzle with crema and lime zest.

Serving Ideas

• Cilantro-lime rice or Mexican red rice
• Crisp green salad with avocado dressing
• Quick pickled red onions and sliced radishes
• Refried beans or charro beans
• Warm tortillas or tortilla chips for scooping

Storage & Reheat

• Fridge: Store airtight 4–5 days. Flavors deepen by day two.
• Freeze: Assemble through Step 5 (with the first cup of cheese mixed in), do not add top cheese, wrap tightly, and freeze up to 2 months. Thaw overnight, add remaining cheese, and bake as directed (add 10–15 minutes).
• Reheat: Microwave individual portions 60–90 seconds, stirring once. For best texture on larger portions, reheat covered at 325°F until hot, then uncover and broil 1 minute to refresh the cheesy top.

FAQs

Can I make this truly “dump-and-bake” without browning?
For flavor and food safety, brown the beef first. If you want zero stovetop work on a busy night, brown it earlier and refrigerate; then it’s dump, stir, cover, bake.

Which cheese melts best?
Monterey Jack melts super creamy and stretchy. Cheddar gives sharper flavor. A Mexican blend (Jack + cheddar) is a great middle ground.

Black beans or pinto beans?
Both work. Black beans hold their shape; pinto beans turn a little creamier. Mix them if you like the best of both.

How do I keep it mild for kids?
Use mild salsa and skip extra chiles. Put hot sauce, chipotle flakes, or pickled jalapeños on the table for spice lovers.

Can I add rice?
Yes stir in 1 to 1½ cups cooked rice at Step 5 and add 2–3 tablespoons extra broth if the mixture seems thick. Bake as written.
