The Birth Of The Single Serving Taco Casserole: A Nostalgic Tale

Back when my kids were little, I was part of a fantastic playgroup. Once a month, our little crew would rotate homes for playdates. While the children engaged in playtime, us parents had the opportunity to catch up and unwind. Every get-together included a communal lunch provided by that month’s host. During one such gathering, a mom served an unforgettable taco casserole that had us all asking for the recipe.

This single serving Taco Casserole recipe takes a cue from that memorable dish. It captures all the essence and flavors of the original, but in a downsized version ideal for one or two people. Crafted to fit a small baking dish, it’s the perfect solution for satisfying those taco casserole cravings without the leftovers.

What Is A Taco Casserole?

Think of taco casserole like a Mexican lasagna! It has layers of seasoned ground beef, melted cheese, and a crunchy base. Instead of pasta, we use tostadas (or broken taco shells) which add a satisfying crunch. This single serving version uses three tostadas layered with the beef and cheese – it’s the perfect mix of taco flavors in an easy-to-make format.

Recipe Variations

Feeling creative? The beauty of this taco casserole is its adaptability. Here are some variations that you can try to suit your taste or dietary preferences:

  • Veggie-Laden: Add diced bell peppers, sweet corn, or black beans to the beef mixture for a more nutritious, colorful dish.
  • Go Lean: Swap out ground beef for ground turkey or even ground chicken for a leaner protein option. You’ll maintain a lot of the flavor while cutting some calories.
  • Cheese Switch-Up: Don’t limit yourself to cheddar. Try using a Mexican cheese blend or even crumbled queso fresco for a different cheesy dimension.
  • Heat Level: If you love heat, consider adding sliced jalapeños between the layers or mixing some hot sauce into your beef mixture.
  • Vegetarian Taco Casserole: Make it vegetarian by using plant-based meat alternatives. You won’t sacrifice flavor while sticking to your dietary needs.

    I really like your recipes for one. The amounts are just right, and I appreciate you putting information about the pan size. Another thing that would be helpful is whether the recipe is freezable or not? I have a friend in another town that I occasionally cook meals for because she has cancer, so this info would be greatly appreciated.

    1. Joanie Zisk says:

      Great idea, thank you Kathy. I’ll look into adding that to some of our recipes.

  2. Debbie says:

    Love this casserole – so creative and adorable. And the idea that it came out of a playgroup makes me smile. I'd make two and eat them both myself:)
