Introduction

This Taco Casserole is a flavorful, hearty dish perfect for busy weeknights. Combining seasoned ground beef, black beans, corn, and melted cheese, it’s a comforting meal that’s easy to customize with your favorite toppings.

A white rectangular baking dish holds a layered casserole with three visible layers: the bottom layer is a thick, browned mixture of cooked beans and vegetables with a slightly chunky texture; the middle layer is a smooth, melted cheese blanket that is golden and bubbly with crispy brown spots along the edges; the top layer is a fresh mix of chopped green lettuce, sliced black olives, and halved red cherry tomatoes spread mainly in the center, drizzled with white creamy sauce in thin lines. The dish sits on a white marbled surface, next to a white and wood-handled utensil. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

1 tbsp avocado oil (or cooking oil of choice)
1 medium onion (1/4″ dice, about 2 cups)
1 large bell pepper (1″ dice, about 1.5 cups)
1 pound ground beef (85/15 lean)
3 tbsp taco seasoning
15 ounce can black beans (drained and rinsed)
2 cups frozen corn
2 cups fresh salsa (from the refrigerated section)
3 cups Pepperjack cheese (grated)
Sour cream, chopped tomatoes or salsa, shredded romaine, corn chips, green onions, olives, avocado (for serving)

Instructions

Step 1: Preheat the oven to 350ºF.
Step 2: Once you’ve finished prepping your ingredients and toppings, heat a large 12-14″ skillet over medium-high heat.
Step 3: When the pan is hot but not smoking, add the avocado oil along with the onion and bell pepper. Sauté, stirring as they brown, until just tender, about 3-4 minutes.
Step 4: Add the ground beef, breaking it up into small bits, then sprinkle the taco seasoning over it. Cook, stirring frequently, until the ground beef is no longer pink.
Step 5: Stir in the black beans, corn, and salsa. Turn off the heat and mix well, then add 1 cup of the grated cheese and stir again.
Step 6: Transfer the mixture to a lightly greased 9″x13″ baking dish and evenly top with the remaining 2 cups of cheese.
Step 7: Bake until the casserole is browned on top and bubbling, about 25-30 minutes.
Step 8: Serve with your desired toppings such as sour cream, chopped tomatoes, shredded romaine, corn chips, green onions, olives, or avocado.

Tips & Variations

For a spicier kick, add chopped jalapeños or a dash of hot sauce to the beef mixture.
Use ground turkey or chicken for a lighter protein option.
Swap Pepperjack cheese for cheddar or a Mexican cheese blend to vary the flavor.
Add cooked rice or quinoa to the mixture for extra bulk and texture.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave until warmed through or place in a 350ºF oven covered with foil for 15-20 minutes to preserve moisture.
