Step‑by‑Step Instructions for Cheesy Low Carb Taco Casserole! Easy & Delicious Dinner
Step 1: Preheat Oven & Prepare Ingredients
Begin by preheating your oven to 375°F (190°C). As the oven heats, take a moment to grease a 9×13-inch baking dish with a bit of olive oil to prevent sticking. Gather and properly prepare all your ingredients: finely dice the yellow onion and bell peppers, and ensure the cream cheese is softened for easy mixing.
Step 2: Brown the Ground Meat
In a large skillet over medium heat, add 2 tablespoons of olive or avocado oil. Once hot, add the 2 pounds of ground beef, browning it for about 7-10 minutes while breaking it into smaller pieces. Cook until the meat is no longer pink, then carefully drain any excess fat to keep your Cheesy Low Carb Taco Casserole from being too greasy.
Step 3: Sauté Aromatics
After the meat is browned, add the diced onion and bell peppers to the skillet. Sauté these vegetables for around 5-7 minutes, stirring occasionally, until they are tender and fragrant. Next, sprinkle in the low-carb taco seasoning and stir for an additional minute to allow the spices to coat the meat and veggies evenly.
Step 4: Simmer Filling
Pour in the can of diced tomatoes with green chilies (undrained) and the ½ cup of water or beef broth to your skillet mixture. Bring this filling to a gentle simmer for about 5-10 minutes. Stir occasionally and taste for seasoning, adjusting with salt and pepper as needed to create a flavor-packed filling for your casserole.
Step 5: Prepare Creamy Mixture
In a medium bowl, blend together the softened 8 ounces of cream cheese, ½ cup of sour cream, and the optional ¼ cup of heavy cream using a hand mixer or spatula until smooth and well combined. Add in the ½ teaspoon of garlic powder and ¼ teaspoon of onion powder, mixing until fully incorporated to create a luscious creamy layer.
Step 6: Combine Layers
Take a portion of the creamy mixture and gently fold it into the skillet with the meat and veggie filling, ensuring everything is evenly coated. Carefully transfer this combined mixture into your greased baking dish, spreading it out evenly to form the base layer of your Cheesy Low Carb Taco Casserole.
Step 7: Assemble Casserole
Next, spread the remaining creamy mixture over the meat layer in your casserole dish, smoothing it out to create a comforting topping. Don’t forget to sprinkle the 2 cups of shredded cheese evenly over the top, ensuring every bite of the Cheesy Low Carb Taco Casserole will be richly cheesy and satisfying.
Step 8: Bake
Place the assembled casserole into your preheated oven and bake for 25-30 minutes. Watch for it to become bubbling and golden on the edges. If the cheese browns too quickly, you can tent the casserole with foil to protect it while it finishes cooking to perfection.
Step 9: Rest, Garnish, & Serve
Once baked, remove the casserole from the oven and let it sit for about 5-10 minutes. This resting time allows the flavors to settle. Before serving, feel free to garnish with fresh cilantro, avocado slices, or a dollop of sour cream for extra flare. Serve warm and enjoy this delightful Cheesy Low Carb Taco Casserole!

Cheesy Low Carb Taco Casserole Recipe FAQs
What should I look for when selecting ripe vegetables?
Absolutely! When choosing bell peppers and onions, look for firm, brightly colored peppers without any dark spots or wrinkles. The onions should be dry and firm, avoiding any with soft or mushy areas as those may not hold up during cooking.
How can I store leftovers properly?
For optimal freshness, store any leftover Cheesy Low Carb Taco Casserole tightly covered in the refrigerator for up to 3-4 days. Ensure the casserole is completely cooled before covering to prevent excess moisture, which can make the topping soggy.
Can I freeze Cheesy Low Carb Taco Casserole? How?
Very! To freeze, first let your casserole cool completely. Then, cut it into serving portions and place them into airtight containers or freezer bags, labeling each with the date. You can freeze it for up to 3 months. When ready to enjoy, thaw the casserole overnight in the fridge, then reheat in the oven at 350°F (175°C) for about 20-25 minutes or until warmed through.
What if my casserole is too dry or too wet?
If your casserole turns out too dry, consider adding an extra splash of beef broth or a dollop of sour cream when reheating. On the other hand, if it’s too wet, you can bake it a little longer to evaporate excess moisture—just keep an eye on the cheese topping to prevent burning!
Are there any dietary considerations for pets or allergies?
It’s important to note that while the Cheesy Low Carb Taco Casserole is a family-friendly dish, ingredients like onions and garlic can be harmful to pets. Always keep your furry friends away from any leftovers. Additionally, watch for common allergens like dairy if you’re serving guests with allergies.
What can I use as substitutions for the ground meat?
You can easily customize your Cheesy Low Carb Taco Casserole by substituting the ground beef with ground turkey, chicken, or even plant-based alternatives like lentils or chopped mushrooms. This allows you to cater to different dietary preferences while keeping your casserole delicious!
