Ingredients
Gather ’round, folks! Here’s what you’ll need to whip up this amazing Doritos Taco Casserole. Don’t worry, these are all pretty standard pantry staples, and the star of the show, of course, is the Doritos!
- 1 pound lean ground beef: This is our savory base.
- ½ yellow onion, diced: For that sweet, aromatic goodness.
- 1 teaspoon minced garlic: Because garlic makes everything better, right?
- 1 packet taco seasoning: The secret weapon for instant Tex-Mex flavor!
- 12 ounce bag frozen corn: Adds a pop of sweetness and texture.
- 14.5 ounce can petite diced tomatoes with green chilies, undrained: These little gems bring a bit of tang and a mild kick.
- 1 cup sour cream: For creaminess and a smooth finish.
- 2 cups finely crushed Doritos: These go into the casserole to soak up all those delicious juices.
- 1 cup loosely crushed Doritos: For that irresistible crunchy topping!
- 3 cups Mexican blend cheese: Melty, gooey perfection.
- 1 cup black beans (optional): If you love black beans, toss ’em in for extra heartiness!
How to Make It
Alright, let’s get cooking! This is where the magic happens. Just follow these simple steps, and you’ll have a dinner winner in no time.
- Brown the Beef: Grab a large skillet and set it over medium-high heat. Add your ground beef and cook until it’s nicely browned. Now, drain off any extra grease – we want flavor, not grease!
- Soften the Aromatics: Toss in your diced yellow onion and minced garlic. Cook these with the beef, stirring occasionally, until the onion starts to soften up, usually about 5-7 minutes. Your kitchen should be starting to smell amazing!
- Spice it Up: Stir in that packet of taco seasoning. Let it cook for just one more minute, stirring constantly. This helps the flavors really bloom.
- Add the Goodies: Now for the fun stuff! Add the frozen corn, the undrained can of diced tomatoes with green chilies, and if you’re using them, your black beans. Give everything a good stir and bring it all to a gentle simmer.
- Get Creamy and Crunchy: Remove the skillet from the heat. Stir in the sour cream until it’s nicely combined. Then, fold in the 2 cups of finely crushed Doritos. Mix everything together until it’s well combined. I like to gently fold them in so they don’t turn into total mush, but they’ll still absorb all that deliciousness.
- Preheat the Oven: Get your oven preheating to 375°F (190°C). While it’s heating up, go ahead and grease a 9×13 inch baking dish.
- Into the Dish: Pour your savory, creamy mixture evenly into the prepared baking dish.
- Cheese, Please! Sprinkle that glorious Mexican blend cheese evenly over the top of the casserole. Don’t be shy!
- The Crunchy Crown: Now, top it all off with that 1 cup of loosely crushed Doritos. This is what gives you that incredible texture contrast.
- Bake to Perfection: Pop the dish into your preheated oven and bake for about 20-25 minutes. You’re looking for that cheese to be all melted and bubbly, with the Doritos on top turning golden brown and irresistible.
- Garnish (Optional but Recommended!): Once it’s out of the oven, let it sit for a few minutes. Then, feel free to garnish with some fresh sliced green onions, a few diced tomatoes, some shredded lettuce, creamy avocado, or an extra dollop of sour cream. It’s like a little party on top!
Substitutions & Additions
This casserole is already fantastic, but you know me – I love to play around! Here are a few ideas to make it your own:
- Different Chips: While Doritos are classic, you could try tortilla chips or even crushed Fritos for a different flavor profile.
- Protein Power: Swap the ground beef for ground turkey or chicken for a lighter option. You could even use shredded rotisserie chicken!
- Spice Level: If you like it spicier, add a can of diced green chilies to the mix, or a dash of hot sauce. For milder flavor, use Rotel diced tomatoes without the chilies.
- Veggies: Feel free to add sautéed bell peppers, corn (if not using frozen), or a can of drained pinto beans along with the black beans.
- Cheeses: Cheddar, Monterey Jack, or a spicy pepper jack would also be delicious.
Tips for Success
A few little tricks to ensure your Doritos Taco Casserole is a showstopper every time!
- Crushing the Doritos: For the finely crushed Doritos that go inside, I like to put them in a Ziploc bag and crush them with a rolling pin or the bottom of a glass. For the topping, just a gentle crush by hand is perfect for those bigger crumbles.
- Don’t Overcook: Keep an eye on it while it’s baking. You want the cheese melted and bubbly, not burnt.
- Prep Ahead: You can totally assemble the casserole (up to step 8, before adding the topping) a day in advance. Just cover it tightly and keep it in the fridge. When you’re ready to bake, let it sit at room temperature for about 30 minutes, add the topping, and bake as usual, possibly adding a few extra minutes to the baking time.
- Drain Well: Making sure you drain the grease from the beef and any excess liquid from the tomatoes is key to a good texture and preventing a watery casserole.
How to Store It
Got leftovers? Lucky you! This Doritos Taco Casserole reheats beautifully. Once cooled, store any leftovers in an airtight container in the refrigerator for up to 3-4 days. To reheat, you can microwave individual portions or gently warm it in a covered baking dish in a low oven (around 300°F or 150°C) until heated through.
FAQs
- Can I make this vegetarian? Absolutely! Simply omit the ground beef and add an extra can of black beans or corn, or some sautéed vegetables like bell peppers and zucchini.
- What kind of Doritos should I use? Nacho Cheese Doritos are the classic choice and what I recommend for that signature flavor. However, Cool Ranch would also be delicious!
- Can I freeze this casserole? Yes, you can freeze the assembled and unbaked casserole. Cover it tightly with plastic wrap and then foil. When ready to bake, thaw it completely in the refrigerator overnight, then bake as directed, adding a bit more time if needed.
