My spectacles were steamed up again, just from leaning over the skillet, trying to eyeball if that diced onion was truly see-through yet. Lord, that happens every time. A little bead of water ran down my cheek, not from crying, mind you, just kitchen heat.
And then the dog, bless her heart, bumped my leg right as I went to stir, sending a rogue piece of onion flying onto the floor. She sniffed it, then looked at me like I was trying to poison her. Some dogs.
Making a good meal often means a little mess. Sometimes a lot of mess. But itโs worth it, especially for something easy and comforting like this Keto Beef Taco Bake.

Ingredients for Low Carb Taco Casserole

You’ll need a good tablespoon of avocado oil. Or olive oil if thatโs what you keep on hand. Don’t be shy with it, a little fat is flavor.
One small onion, diced up fine. Don’t dice it too big, nobody wants a mouthful of raw onion.
Four cloves of garlic, minced. Get it real small. That garlic makes things sing. It just does.
A pound of lean ground beef. You can use fattier if you want, just drain it well. I always prefer lean for this Keto Beef Taco Bake.
One packet of your favorite taco seasoning. Don’t make your own unless you really want to. The packets are easy.
Ten ounces of diced tomatoes with green chilis. Rotel, thatโs what I mean. Don’t drain it. The liquid is good.
Two cups of shredded Mexican blend cheese. Or Colby Jack. Whatever you got that melts well. Lots of cheese.
For toppings, you can use sliced tomatoes, avocado, or sour cream. My grandkids like sour cream and nothing else. Pick your battles.
How to make Keto Taco Casserole with Ground Beef
First thingโs first, get that oven hot. Set it to 400 degrees Fahrenheit. It needs to be ready when you are.
Grab a big skillet. Heat the oil in it over medium heat. Don’t get it smoking, just a nice warmth.
Toss in your diced onion and that minced garlic. Cook them until the onion turns clear. About five to eight minutes, stirring so it doesnโt stick.
Next, add your ground beef to the pan. Break it up with your spoon as it cooks. You want it crumbled, not big chunks.
Let that beef cook through, about eight minutes. No pink left in it. Drain any fat if there’s a lot.
Stir in your taco seasoning then. And a quarter cup of water. Let it simmer for a minute, so the flavors can get to know each other.
Spoon that meaty mixture into a casserole dish. Spread it out nice and even. This makes the best easy keto taco bake.
Now, stir in the Rotel. And a cup of that shredded cheese. Mix it all up in the dish.
Finally, take the rest of your cheese. Sprinkle it all over the top. Make sure it’s covered.
Slide that dish into your hot oven. Let it bake for twenty minutes. Or until the cheese is bubbling and golden on top.
That’s how you get this delicious ground beef taco casserole keto style. So simple.

If you have leftovers of this Keto Beef Taco Bake, youโre in luck. They taste mighty fine the next day. Sometimes even better.

Itโll keep in the fridge for three or four days. Just reheat a serving in the microwave. Or pop the whole thing back in the oven, low and slow.
This is a great dish for planning ahead. You can cook the beef mixture on a Sunday. Then assemble and bake it later in the week for a quick keto friendly taco recipes meal.
