Best Way To Cook Breasts Chicken That Will Be Shredded

There are quite a number of ways you can cook chicken that will be shredded. I chose to poach the chicken breast, but you can also cook chicken in an instant pot or slow cooker.

In fact, you can even choose the chicken breast from a rotisserie chicken if you want to save some time.

How To Quickly Shred Chicken

I have several ways you can shred your chicken breasts easily:

• Two-Forks: Once the allotted cooking time has passed, you’ll shred the chicken by taking it out of the crockpot, oven dish, or Instapot and using the two-fork method, where you hold one end of the chicken while you pull the other fork across the flesh of the chicken until it shreds.
• Food Processor: If you have a large food processor, this method works like a charm. Add the chicken and process it until it shreds.
• Stand-up Mixer/Hand Mixer: You can also shred the chicken in a stand-up mixer with the paddle attachment or a handheld one. This happens to be my favorite since it’s so quick.

How To Make Keto-Friendly Chicken Taco Casserole

Making this gluten-free chicken taco casserole really is quick and simple. You’ll start off by cooking your chicken and then preheating the oven to 350 degrees F.

Next, you’ll cook the frozen cauliflower rice according to the package instructions.

If frozen cauliflower rice is not an option for you, you can make our recipe for cilantro lime keto cauliflower rice.

Then, in a large bowl, combine the cooked cauliflower rice with the lime juice and the chopped cilantro. Spread the cilantro lime cauliflower rice evenly onto a 9×13 greased baking dish.

Combine the shredded chicken with the dry spices or taco seasoning of choice in a medium bowl and set it aside.

Complete your taco casserole by sprinkling the chopped onions over the surface of the cauliflower rice.

Next, add the seasoned shredded chicken to the onion and cauliflower rice, making sure to distribute the chicken evenly.

Then, it’s time to prepare the creamy salsa sauce. To do so, mix together the tomato sauce, diced can of tomatoes, green chilies, sour cream, and heavy cream until fully combined.

Pour the creamy salsa sauce evenly over the chicken and cauliflower rice in the baking dish.

Next, sprinkle 2 cups of the shredded cheese over the surface of the chicken taco casserole. If adding the raw jalapeños, evenly distribute them over the casserole. Then sprinkle with the green onions.

Then sprinkle the remaining 1/2 cup of shredded cheese on top of the casserole.

Pop your keto casserole in the oven and bake for 35–40 minutes until the casserole is hot and bubbly and the top is golden brown.

Recipe Variations & Tips

Feel free to use leftover rotisserie chicken in place of the chicken breasts. It’s an easy way to speed up the cooking process.

Customize your cheese to your personal preference. I chose to use a Mexican blend, but you could easily swap it for Monterey Jack, Colby, or cheddar cheese.

Instead of using a can of diced tomatoes, green chilies, and tomato sauce, you can use your favorite prepared low carb friendly salsa or even some of our homemade keto Guatemalan salsa. Or use salsa verde for another flavor profile.

You can also swap out the chicken in the casserole for pork cooked in a slow cooker.

Add 1/2 teaspoon of chipotle powder for a little smokey heat.

Feel free to use sugar-free taco seasoning for this low-carb taco casserole instead of the listed spices.

Add more of your favorite taco toppings, like sliced black olives, shredded lettuce, diced tomatoes, green peppers, and avocado slices!

What To Serve With A Low-Carb Taco Chicken Casserole

This keto taco bake is a complete meal that can be enjoyed without any sides.

However, if you want to round out your meal further, you can serve this with a simple salad or side.

Here are some sides to consider:

• Keto tortillas 
• Keto coleslaw 
• Keto red cabbage slaw with carrots
