Years ago, when my kids were little, I was part of a playgroup where we’d take turns hosting lunch during our monthly meetups. One day, a mom served a taco casserole that was so good we all asked for the recipe. This single serving version is inspired by that dish, capturing the same bold flavors in a smaller portion. It’s like a Mexican lasagna—layers of seasoned ground beef, melted cheese, and crispy tostadas instead of pasta. Baked until bubbly, it’s the perfect way to enjoy taco casserole without leftovers.

- Olive Oil: Used for cooking the onions and garlic.
- Onions & Garlic: These build flavor in the beef mixture, so don’t skip them.
- Ground Beef: Use lean ground beef for the best texture. If using higher-fat beef, drain excess grease after cooking. Leftover ground beef? Use it in Hamburger Soup, Cottage Pie, or Taco Soup.
- Salsa: Adds moisture and extra flavor to the casserole. Choose mild, medium, or hot, depending on your preference. Extra salsa can be used in Black Bean Soup or on a Southwest Wrap.
- Taco Seasoning: A blend of spices that gives the beef its classic taco flavor. Use your favorite brand or make your own.
- Tostadas: Crispy layers that add texture. If you don’t have tostadas, crumbled taco shells work too.
- Cheddar Cheese: Adds a rich, melty layer. Use sharp cheddar for the best flavor.
For Topping (Optional): Sour cream, black olives, extra salsa, or guacamole for added flavor and texture.
Recipe Variations
This taco casserole is easy to customize. Here are a few ways to change it up:
- Add More Vegetables: Stir in diced bell peppers, corn, or black beans for extra flavor and texture.
- Use a Different Protein: Swap the ground beef for ground turkey or chicken for a leaner option.
- Try a New Cheese: Use a Mexican cheese blend or crumbled queso fresco instead of cheddar.
- Make it Spicy: Add sliced jalapeños between the layers or mix hot sauce into the beef.
- Vegetarian Version: Use a plant-based meat alternative for a meatless variation.

Delicious, as always. I used broken tortilla chips instead of the taco shells.
This is my favorite recipe from the site so far! I’ve tried four, I think, so not too many yet. I used slightly crunched up tortilla chips because I didn’t have tostadas or shells. Worked great!!
Iโve made this for many years for my family. Just add 2 more layers of meat and tortillas. Weโve always called this โTortilla Towerโ.
Love the ODK recipes! I make a similar dish but with corn tortillas. I love it, but it turns out very soft. Does using tostadas keep it crunchy? TYIA.
The tostadas give some crunch but because of the fillings, the tostadas have some softness to them but not as much as softer corn tortillas will.
This recipe is very tasty. I made it exactly as written and topped with tomato,avocado and sour cream and ate the whole darn thing lol
I brown a pound of ground beef or turkey and add the taco seasoning. Portion out enough meat for casserole (1/4 of mixture) and several small packages for taco salad and freeze. So nice to just grab from freezer and use. Takes no time to thaw in such small portions!
Great recipe! I could only finish half. Used the rest of meat as sandwich filling. Makes a great “Sloppy Taco Joe”!
