How perfect is this mini taco casserole? It’s a wonderfully portioned casserole that’s prepared like a “taco lasagna”. Layers of beef and cheese are sandwiched between crispy tostadas or taco shells, baked and topped with salsa, sour cream, and black olives.

Years ago, when my children were small, we belonged to a wonderful playgroup. Every month we would get together and visit one another’s homes with our kids in tow and while the kids played together, the moms would get the chance to sit, relax a little and be able to visit with each other. It was such a nice break for us moms and the kids always had fun playing with each other.

Our playgroup always included lunch and whoever was hosting the playgroup, provided the lunch. This easy Taco Casserole For One recipe comes from one of the lunches from a playgroup many years ago. I can remember asking for the recipe and since so many of the moms did, our friend copied her taco casserole recipe down for all of us.

I keep my old recipes from friends and magazines in a large binder in my kitchen and I came across that old Taco Casserole recipe the other day. I made it for my family and not surprisingly, they loved it.

While I was making the casserole I thought it would also make a great single serving recipe. A perfectly portioned Taco Casserole For One.

What is a Taco Casserole?

This single serving Taco Casserole is prepared very much like a lasagna.  Instead of noodle layers between the spiced ground beef, I used store-bought tostadas. The tostadas I used fit perfectly in my round and square baking dishes.

The dishes I use hold 3 tostadas with the meat and cheese filling between the layers.  If you can’t find tostadas at your grocery, cracked taco shells would work well too.

How to make a Taco Casserole

Step 1

Brown the ground beef in a pan along with chopped onions, garlic and taco seasoning.

Pro Tip: You can use store bought taco seasoning if you’d like, but if you have an extra minute and already have the ingredients on hand, you might just want to make your own. Homemade taco seasoning is so easy to make.  I’ve provided the ingredients and directions below.

Step 2

Place a tostada on the bottom of a small baking dish, then spoon the spicy ground beef over the top and add shredded cheddar cheese.

Step 3

Top the meat and cheese mixture with another crispy tostada.

  1. Joanie…thank you so much for these wonderful recipes. I work long stressful hours and basically only have time and energy to eat out. That’s a shame because I love to cook but didn’t want to deal with huge amounts of left-overs…not to mention the food cost in preparing for one. I was so impressed when I ran across your recipes that I raced out to Home Goods and found the little white dishes exactly like yours and ….seriously…my life has changed. Now when I trot my lunch out at work, my co-workers are amazed at what I bring to eat! !!! Naturally I told them about your recipes so now we are all well-fed happy campers. Thanks again for all the work you put into this!!

    1. Hi Susan, thank you so much for the kind words. I’ve found so many mini baking dishes at Home Goods, it can be a great place to find dishes at quite a discount. I’m so very happy that you are enjoying the recipes and thank you so much for letting me know. Your comment has completely made my week – thank you!

  2. 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.

  3. I cant wait to make this. I only have one to feed (Myself). So happy it is scaled down to feed one. I will let you know how it turns out. Thanks for sharing.

  4. Just made a double batch for the hubby and myself on a lazy evening. Tasted great while making, although I left out the garlic altogether … can’t wait for the finished dish! THANK YOU!

  5. We used to have a playgroup too! It was the best idea ever! Wish mine was still little to attend those weekly meetings again!
    This single serve taco casserole sounds amazing! No wonder everyone asked for the recipe.
