- 1 can (15 oz) black beans, drained and rinsed
- 1 tbsp all-purpose flour
- 1 ¼ cups milk (whole or 2%)
- 1 ½ cups shredded cheddar cheese
- ½ cup shredded Monterey Jack or Pepper Jack cheese
- 1 cup salsa (medium or hot)
- 1 can (4 oz) diced green chilies
- ½ packet taco seasoning (about 1 tbsp)

Step-by-Step: How to Make Spicy Mexican Mac and Cheese Casserole
1. Cook the Pasta
Bring a large pot of salted water to a boil. Cook the pasta until just al dente, according to package directions. Drain and set aside.
2. Brown the Ground Beef
In a large skillet, heat olive oil over medium heat. Add the ground beef and cook until browned, breaking it up as it cooks. Stir in the garlic and cook for another 30 seconds. Drain excess fat if needed.
3. Make the Cheese Sauce
Push the beef to one side of the skillet and sprinkle the flour into the pan. Stir to combine with any remaining fat and cook for 1 minute. Slowly whisk in the milk and bring to a gentle simmer. Stir in the cheddar, Monterey Jack, taco seasoning, salsa, green chilies, and jalapeños (if using). Mix until the cheese melts and the sauce is smooth.
4. Mix in Beans and Pasta
Add the black beans and cooked pasta to the skillet, stirring everything together until fully coated and evenly distributed.
5. Assemble the Casserole
Transfer the mac and cheese mixture to a greased baking dish. Spread evenly and top with crushed tortilla chips or panko for added crunch.
6. Bake Until Bubbly
Bake at 375°F (190°C) for 20–25 minutes, until the cheese is bubbling and the top is golden. Broil for an additional 1–2 minutes if you want an extra crispy topping—just don’t walk away!
7. Garnish and Serve
Let rest for 5 minutes, then garnish with sour cream, avocado, cilantro, or green onions. Scoop and serve hot!
Tips for the Best Spicy Mac and Cheese Casserole
- Don’t overcook your pasta—al dente is best so it stays firm after baking.
- Use freshly shredded cheese for the best melt and flavor.
- Adjust spice levels with your choice of salsa, extra jalapeños, or a dash of hot sauce.
- Add extra mix-ins like corn, sautéed peppers, or chopped spinach if desired.
- Double it and bake in a bigger dish if feeding a crowd!
Fun Customization Ideas
- Swap the Protein: Use ground turkey or shredded chicken instead of beef.
- Switch Up the Cheese: Try queso fresco, cotija, or smoked gouda for unique flavor profiles.
- Make It Meatless: Leave out the beef and add extra beans and veggies for a vegetarian version.
- Sneak in Veggies: Mix in diced zucchini, bell peppers, or spinach for added nutrients.
- Turn It into Brunch: Crack in a few eggs before baking for a spicy breakfast bake!
