Ingredients for Your Low Carb Taco Casserole

Alright, letโs talk about what you need. Nothing fancy, just good, honest ingredients. Thatโs the secret to any decent meal, if you ask me.
You’ll need a tablespoon of avocado oil or regular olive oil. Either works. Just something to get the onion and garlic going in the pan.
One small onion, diced up. Donโt get fussy with the dice, just chop it fine enough. Four cloves of garlic, minced. I always use a little extra myself.
A pound of lean ground beef. Any kind you got. This is the backbone of your keto ground beef casserole.
One packet of taco seasoning. Keeps things simple. Ten ounces of diced tomatoes with green chilis, like Rotel. Gives it a little kick.
Two cups of shredded Mexican blend cheese or a Colby jack. The cheese pulls it all together. And for toppings? Sliced tomatoes, avocado, or a dollop of sour cream. Whatever you fancy.
How to Make Easy Keto Taco Casserole
First thing, get that oven hot. Set it to 400 degrees. Donโt dilly-dally.
Grab a big skillet. Put your oil in there and let it get warm over medium heat. When it shimmers, youโre ready.
Throw in the diced onion and garlic. Watch it, don’t let it burn. Cook it until the onion turns clear, about five to eight minutes. Stir it so nothing sticks.
Add the ground beef to the pan. Break it up with your spoon. Cook it good until itโs all browned through. This usually takes about eight minutes.
Drain any grease you see. No need for extra fat. Stir in that taco seasoning and a quarter cup of water. Let it simmer a minute, let those flavors get to know each other.
Spoon that beef mixture into a casserole or baking dish. Spread it out even. Now, stir in the Rotel, all those diced tomatoes and green chilis. Mix it with one cup of shredded cheese right there in the dish.
Finally, spread the rest of the cheese on top. Make sure itโs a good, thick layer. Thatโs what gets golden brown and bubbly.
Slide it into your hot oven. Bake it for 20 minutes. Or until the cheese melts and gets a nice golden crust. This Keto Beef Taco Bake will smell so good, everyone will come running.
Tips for the Best Keto Beef Taco Bake
Don’t rush the onions and garlic. Thatโs where a lot of the flavor starts. Let them soften properly, but keep an eye on the garlic. It goes from perfect to burnt mighty fast. Takes a minute to turn bitter.
A hot pan helps brown the beef quicker. Don’t crowd the pan if you’re doing more than a pound. It’ll steam instead of brown.
Always drain the grease from your ground beef. Unless you like a greasy casserole, and who does? Nobody. A good keto ground beef casserole is flavorful, not swimming in fat.
If you don’t have Rotel, use a can of diced tomatoes and add a chopped jalapeรฑo. Just remove the seeds if you donโt want too much heat. This cheesy taco casserole is adaptable.
Don’t be shy with the cheese on top. Thatโs what makes a taco bake recipe so good. The crusty, melted part is the best.
Make sure your oven is truly pre-heated. An oven that’s not hot enough will give you sad, pale cheese. You want that bubbly, golden goodness on your Keto Beef Taco Bake. For more Keto Beef Taco Bake tips and variations, check my archives.
