3) Ingredients for Keto Taco Casserole

1 lb ground beef: I always go for the 85/15 ratio, it has just enough fat to keep things juicy without swimming in grease.

1 small onion, diced: Adds a bit of sweetness and helps mellow the meat. Don’t skip this. Trust me.

1 bell pepper, diced: Adds crunch, color, and makes me feel like I’ve included a vegetable (win).

2 cloves garlic, minced: You could add more. I won’t stop you. Garlic is life.

1 tbsp taco seasoning: You can use a packet, but I like to mix my own with cumin, paprika, and chili powder.

1/2 tsp salt: Just enough to bring out the flavor without making you reach for water every five seconds.

1/4 tsp black pepper: Adds a subtle bite that balances the richness of the beef and cheese.

1/2 cup tomato sauce: This helps create a soft, saucy base that ties the whole casserole together.

1/4 cup sour cream: The secret weapon. Creamy, tangy, and unexpectedly perfect in this mix.

1 1/2 cups shredded cheddar cheese: Go sharp, and don’t be shy. This is where comfort lives.

1/2 cup sliced black olives (optional): If you love a little brine, toss them in. If not, skip it. No pressure.

1/4 cup chopped green onions (for topping): Adds a pop of color and a fresh note that cuts through the richness.

1 sliced avocado (for topping): Totally optional, but I swear it makes the plate feel “done.”

4) How to Make Keto Taco Casserole

Step 1. Preheat the oven to 375°F. Trust me, you want it hot and ready once everything’s mixed.

Step 2. In a large skillet, brown the ground beef over medium heat. Drain the fat but keep the flavor.

Step 3. Add the onion, bell pepper, and garlic. Let them cook together for about 5 minutes, until softened and fragrant.

Step 4. Stir in the taco seasoning, salt, black pepper, and tomato sauce. Let it simmer for 3 minutes so the flavors meld.

Step 5. Remove from heat, then stir in the sour cream. This is where things get creamy and dreamy.

Step 6. Pour the whole thing into a greased 8×8 casserole dish. Smooth the top just enough to keep the cheese from falling into craters.

Step 7. Sprinkle cheddar cheese evenly across the top. Add olives now, if using.

Step 8. Bake for 20 minutes uncovered, or until the cheese is bubbling and golden at the edges.

Step 9. Pull it out and let it rest for 5 minutes. Top with green onions and avocado before digging in.

5) Tips for Making Keto Taco Casserole

If you want easy low carb recipes that don’t taste like they came from a diet book, here’s how to make this one even better. First, don’t overcook the beef. Dry meat equals a dry casserole. Brown it just until it’s no longer pink.

Second, use freshly shredded cheese if you can. Pre-shredded works, but it’s coated in starch to prevent clumping. That starch doesn’t melt as cleanly, and sometimes you can taste it. Shred it yourself and thank me later.

Third, layer in the love. Stirring in the sour cream after the tomato sauce gives you a lush texture that doesn’t break down during baking. It holds the whole thing together without turning to mush.

6) Making Keto Taco Casserole Ahead of Time

I get it. Life’s busy. Sometimes, you need dinner to be waiting for you, not the other way around. This dish fits the bill. You can prep the whole thing a day ahead, pop it in the fridge, and then bake it when you’re ready.

If you do prep it ahead, don’t add the cheese just yet. Cover it with foil, stash it in the fridge, and then add cheese right before baking. That way, you still get that golden crust without the soggy middle.

I’ve even frozen this in portions and reheated it for lunch. If you’re building out your easy low carb recipes for meal prep, this one’s a winner.

7) Storing Leftover Keto Taco Casserole

Leftovers? You’ll be lucky if there are any. But if you do have some, scoop them into an airtight container and keep them in the fridge for up to four days. The flavor gets even deeper overnight.

When reheating, add a little splash of water or broth before microwaving. It keeps things moist and stops the cheese from getting rubbery. You can also reheat it in the oven at 325°F for about 10 minutes if you’re feeling patient.

And yes, this reheats well enough to go straight onto your list of easy low carb recipes for the week.
