Ortega Taco Casserole Recipe | Easy & Cheesy
Craving a cozy, comforting, and flavor-packed dinner that the whole family will love? My Ortega Taco Casserole Recipe is the answer! This dish brings all the zesty flavors of tacos into a cheesy, oven-baked casserole that’s both hearty and easy to make. Perfect for weeknight dinners, potlucks, or game nights, it’s a recipe that satisfies cravings and gets rave reviews every single time.
Step-by-Step Preparation
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C). Grease a 12×8-inch baking dish with a light coating of cooking spray or butter to prevent sticking.
Step 2: Cook the Meat Mixture
In a large skillet, cook 1 lb ground beef, chopped onion, and garlic over medium heat until the meat is browned and the onion is soft. Drain any excess grease for a lighter casserole.
Step 3: Add the Flavors
Stir in 1 cup of water, Ortega taco sauce, green chiles, sliced olives, and the Ortega Taco Seasoning Mix. Let the mixture simmer for 3–4 minutes, allowing the flavors to blend into a rich, taco-inspired sauce.
Step 4: Layer the Casserole
- Place half of the tortilla shells (or crushed chips if using) on the bottom of your greased baking dish.
- Spread half of the meat mixture on top.
- Sprinkle with 1 cup shredded cheddar cheese.
Repeat the layers with the remaining tortillas, meat mixture, and cheese.
Step 5: Bake to Perfection
Bake uncovered for 20–25 minutes, or until the casserole is bubbly and the cheese is melted into gooey perfection.
Step 6: Garnish and Serve
Top with fresh tomatoes, green onions, and the remaining olives for a burst of freshness and color.
Serving Suggestions
This casserole is already a complete meal on its own, but pairing it with a few sides can take it to the next level:
- Fresh Salad: A crisp green salad with lime vinaigrette balances the cheesy richness.
- Spanish Rice or Mexican Rice: A classic side dish that complements the taco flavors.
- Corn on the Cob or Elote (Mexican Street Corn): Adds a smoky, creamy touch.
- Toppings Bar: Set out bowls of sour cream, salsa, guacamole, and jalapeños so everyone can customize their serving.

Variations to Try
One of the best things about this recipe is its flexibility. You can switch it up depending on what you have on hand or your family’s preferences:
- Protein Swap: Use ground turkey, chicken, or even shredded rotisserie chicken instead of beef.
- Vegetarian Version: Skip the meat and bulk it up with black beans, corn, and sautéed bell peppers.
- Spicy Kick: Use Ortega Hot Taco Sauce or pepper jack cheese for extra heat.
- Low-Carb Option: Replace tortillas with thinly sliced zucchini or bell peppers for a lighter version.
- Breakfast Twist: Add scrambled eggs and breakfast sausage for a Tex-Mex morning casserole.
Pro Tips for the Best Casserole
- Use lean ground beef (90/10 or 93/7) to cut down on grease while keeping the flavor.
- Layer evenly so each bite has a perfect balance of tortillas, meat, and cheese.
- Let it rest for 5 minutes after baking; this helps the casserole set and makes serving easier.
- Double the recipe if you’re feeding a crowd; it’s always a hit at potlucks and family gatherings.
Storage Instructions
Keeping Leftovers Fresh
If you have leftovers (and trust me, they taste even better the next day!), cover the casserole dish with foil or transfer portions into an airtight container. Store in the refrigerator for up to 3–4 days.

Reheating Tips
For the best results, reheat in the oven instead of the microwave to keep the cheese melty and the tortillas from getting soggy. Cover with foil while reheating to prevent drying out.
