Here at Fed & Fit we LOVE a good casserole. You may think of casseroles as dishes from the 60s and 70s that combine a bunch of random ingredients together with questionable cream-of-something soup, but that’s not how we do it around here! In fact, casseroles are an amazing vehicle for getting real food on the table each week. Why?

First, casseroles are easy to make in bulk, meaning you can have enough for dinner one night and still have leftovers for lunch the next day, or you can even freeze any extras.

Second, they are a great way to get your veggies in! We’ve added kale and bell pepper in this casserole, but you could also easily add some zucchini or even shredded carrots to bulk it up a bit more.

Finally, we love casseroles because they just scream comfort food, and good, comforting food makes the transition to eating healthy SO much easier.

Taco Casserole Ingredients

Okay, so let’s talk about this beef taco casserole. This dish is based on one of our most popular casseroles – cheeseburger casserole! Y’all loved that one so much that we wanted to put a new spin on it, and this time we landed on Tex-Mex style. Here’s what you’ll need to make it:

  1. Frozen Hash Browns. We used frozen hash browns (easy button!) to form the crispy crust on this beef taco casserole and to make it grain-free, but if hash browns aren’t your thing, you can easily sub white rice or cauliflower rice for a lower-carb option.you are low-carbing (see the recipe notes for details).
  2. Ground Beef. For this taco casserole, we really wanted to imitate the flavors of a classic crispy taco, so we decided to use ground beef instead of chicken.
  3. Veggies. As mentioned before, casseroles are a great way to sneak in some extra veggies! For this one you’ll need onion, garlic, a red bell pepper, and one bunch of lacinato kale.
  4. Tomato Sauce + Seasonings. For this recipe, we wanted to replicate traditional ground beef flavors without relying on a taco seasoning packet, which can have gluten, sugar, and artificial ingredients like maltodextrin. A combination of tomato sauce, paprika, chili powder, cumin, and oregano gets the job done even better than the classic packet.

How to Make

Now that you’ve got your seasonings all rounded up, it’s time to make the casserole! Here’s what you’ll do:

  1. Make the hash browns. The first step is to cook up your frozen hash browns. We are looking for a crispy layer of potatoes here! You’ll add oil to the pan (we like avocado oil the best) and cook the hash browns for about 5 minutes, then flip them and cook an additional 3-4 minutes. After that, you can remove them from the pan and set them aside.
  2. Cook the onions, garlic, and bell pepper. In the same pan you made the hash browns in, add a little bit more oil and cook the diced onions, minced garlic, and red bell pepper for about 4 minutes until the onion is translucent and the bell pepper has started to soften. This will add great flavor to the beef layer of the taco casserole.
  3. Brown the ground beef. Next, add the ground beef to the pan along with a little salt and pepper, and cook for about 6-8 minutes, until the beef is fully cooked through.
  4. Add the sauce ingredients. Once the beef is browned, it’s time to bring everything together. Pour the tomato sauce, a little bit of water, and the spices over the beef and stir to combine. Once that is fully mixed, stir in the shredded kale. Let everything cook for about 2-3 minutes until the kale is just wilted and has turned bright green in color, then remove it from heat.
  5. Assemble and bake the casserole. To assemble the casserole, press the hash browns into the bottom of the pan, then pour in the beef mixture, and top everything with cheese. Bake it for 15 minutes at 350 F, then garnish with cilantro and sliced avocado and serve!

Recipe Tips

There are a few things to keep in mind when it comes to making taco casserole. To ensure the yummiest taco casserole possible, be sure to…

Let your hash browns get crispy – this is KEY and takes some patience. Resist the urge to move your hash browns around in the pan, and instead, let them really crisp up in an even layer for 4-5 minutes per side.

Use fresh onion and garlic – while you always have the option of subbing in garlic or onion powder for the real thing, we really recommend sticking to fresh here as it’ll really help to build flavor in the casserole.

Add the kale last – remember that you want the kale to *just* wilt and turn bright green. As soon as you see that happening, remove the casserole from the heat. This will keep it from getting a slimy cooked greens texture.

Taco Casserole Variations

You can swap things out as you desire here! A few yummy swaps would be…

  • Use ground chicken instead of ground beef – if you’re out of ground beef or it just isn’t your thing, feel free to use ground chicken (or turkey!) instead.
  • Use nacho cheese instead of grated cheese – top the casserole with our vegan nacho cheese for a fun spin on the dish!
  • Use any color pepper – feel free to swap the red bell pepper for a bell pepper color of your choice. You could even add some spice by using a diced jalapeno pepper if you’d like!
Can you make this ground beef casserole ahead of time?

Definitely. This is a really great meal to make ahead of time, actually, and can even be prepped and cooked up to 3 days in advance.

Can I freeze this taco casserole?

Yes! This beef taco casserole freezes great. You can either assemble it and freeze it whole, or freeze the individual portions. To reheat, either bake the whole, frozen casserole at 350 F for 50-60 minutes, until fully warmed through or microwave a single portion for 90 seconds or place it in the oven at 350 F for 15-20 minutes.

How long will a ground beef casserole last?

This taco casserole will last up to 5 days in the fridge or even longer in the freezer (see above for freezer instructions!).

Can I make this taco casserole dairy-free?

You can easily leave the cheese off this casserole, but if you’re dairy-free and looking for a good cheese option we’d recommend pouring our vegan nacho cheese on top.

What else can I add to this taco casserole?

Corn, black beans, and diced zucchini would all make great additions to this casserole if you’d like to bulk it up a little bit more!

How to store a beef casserole?

If you’re storing this casserole whole and cooked, consider just putting the lid on the pot (or using aluminum foil if you don’t have a lid) and sticking it in the fridge. If you’re saving leftovers, go ahead and pop them in an airtight container in the fridge.

    This was such a great meal. Easy to put together and great combination of flavors. We couldn’t find shredded potatoes at our grocery store and ended up using tater tots. Mashed them up for the base in the frying pan before putting them in the casserole dish.

    1. What a clever sub to use mashed tater tots! Thank you so much for taking the time to share with us. We are so glad this meal was a hit for you! -Team FF

    This turned out amazing! I made it with Trader Joe’s microwaveable rice on the bottom layer instead of potatoes (time crunch) but it was fantastic. Can’t wait to make it again!

    1. Thank you for taking the time to share this with us, Eva! TJs rice as the bottom layer is such a great time hack! I’m glad you enjoyed! ~Melissa

  3. Would this work well without tomato sauce? Or would you need another “wet” casserole ingredient!

    1. The tomato sauce really helps to make it more of a casserole (vs. just ground meat), but it would still taste good without it, Sophie!

  4. Could you use hash brown patties that are already crisp and not pre-cook them before assembling if you are freezing the dish? I think I would pre-bake them if I was to assemble and serve the same day. I would appreciate your opinion. Thanks.

    Made this tonight for our Whole30 night 1! It is delicious! Great flavor. We used cashew queso on top and it turned out awesome. Subbed a few radishes for half of a red pepper. Excellent! This will be a repeat for us!
