Step‑by‑Step Instructions for Taco Casserole

Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) and grab a 13×9 inch baking dish. Lightly coat the dish with non-stick spray to prevent sticking. This ensures your Easy Walking Taco Casserole comes out perfectly without any hassle. Once prepped, set the baking dish aside while you cook the beef mixture.

Step 2: Brown the Beef
In a large skillet over medium heat, add 1 pound of lean ground beef. Cook until the beef is browned and nearly cooked through, which takes about 5-7 minutes. As it cooks, use a spatula to break the meat into small pieces. When the beef is mostly browned, stir in 1 chopped small onion and sauté until the onion is soft and translucent, around 3-5 minutes.

Step 3: Add Taco Seasoning
Stir in 1 packet of taco seasoning along with ½ cup of water, increasing the heat to bring the mixture to a gentle boil. This step should only take 2-3 minutes. Keep an eye on the mixture as it bubbles, ensuring everything is well combined and coated in the delicious seasoning.

Step 4: Mix in the Goodness
Lower the heat and add 1 can of drained black beans, 1 can of diced tomatoes with green chiles, and ½ cup of sour cream to the skillet. Stir well to combine and cook for an additional 8-10 minutes until the mixture thickens slightly and is heated through. You’ll notice the vibrant colors and aromas as the flavors meld together beautifully.

Step 5: Layer the Casserole
Now it’s time to assemble your Taco Casserole! Start by layering Fritos corn chips evenly across the bottom of your prepared baking dish. Sprinkle 1 cup of shredded cheese on top of the Fritos, followed by the hearty beef mixture. Finish by topping with the remaining cheese, creating a deliciously cheesy crust.

Step 6: Bake to Perfection
Cover the baking dish with foil and place it in the preheated oven. Bake for 15 minutes to allow the flavors to blend together. After 15 minutes, carefully remove the foil and continue baking for another 5 minutes. You’ll know it’s ready when the cheese is bubbly and lightly golden on top, signaling that it’s time to serve.

Taco Casserole Recipe FAQs

Which ground meat should I use for the casserole?
Absolutely! For a flavorful and healthier taco casserole, I recommend using lean ground beef. If you want a lighter option, ground turkey or chicken also works beautifully. Just ensure to cook any variation thoroughly until it’s no longer pink.

How do I store leftovers?
You can store any leftovers in an airtight container in the fridge for up to 3-4 days. Be sure to let the casserole cool completely before sealing it, as this prevents moisture buildup. It’s a fantastic way to enjoy the dish later in the week!

Can I freeze taco casserole?
Yes, you can definitely freeze taco casserole! I often do this for meal prep. Just wrap the cooled casserole tightly in plastic wrap and then aluminum foil, or transfer it to a freezer-safe container. It will keep well for up to 3 months. When you’re ready to eat, simply thaw it in the fridge overnight and reheat at 350°F (175°C) until warmed through—about 20-25 minutes.

What should I do if my casserole is too watery?
Very! If you find your casserole is a bit watery, that can often happen when the tomatoes release their juices or if the beef isn’t fully drained. Next time, make sure to drain the diced tomatoes well and consider adding a thickening agent like cornstarch mixed with a little water before baking. You could also reduce the amount of liquid added, or allow it to cook a little longer to evaporate some moisture.

Can I modify the recipe for dietary restrictions?
Absolutely! This taco casserole is quite adaptable. For a gluten-free option, ensure you use gluten-free tortilla chips instead of Fritos. If you need dairy-free, consider dairy-free cheese or adding more vegetables for taste and texture. Adjusting the seasoning could also cater to those with spice sensitivities—simply use a milder taco seasoning or homemade spice mix!
