How to Make Cauliflower Beef Taco Skillet
Roasting the cauliflower in advance helps pull out some of the excess moisture and creates great flavor.
Roast the Cauliflower
- Place the cauliflower on a large rimmed baking sheet. Drizzle with olive oil and season with a little salt and pepper.
- Roast in a preheated 425 degree F oven for 12 to 14 minutes, or until beginning to brown and barely fork tender. Remove from the oven, toss with a spatula, and set aside.
While the cauliflower is roasting, you’ll have time to get the beef mixture cooking.
Cook the Beef Mixture
- Sauté the onion and bell pepper in a little oil until softened.
- Add the beef and cook, stirring to break it up, until it is cooked through.
- Drain off the excess grease from the skillet and return it to the heat. Add the garlic and seasonings.
Finish and Bake
- Cook, stirring, for about a minute until the beef is well coated with the spices.
- Next, add the tomatoes and the roasted cauliflower and bring the mixture to a low simmer. Then, reduce the heat to low and cover and simmer for about 5 minutes, or until the cauliflower is tender.
- Finally, sprinkle the cheese over the cauliflower beef mixture and transfer the skillet to the oven and broil briefly until the cheese has melted and it is lightly browned in spots.
Tips for the Best Result
- Cut the cauliflower into small pieces: To ensure that the cauliflower will roast evenly and quickly, cut it into small bite-sized pieces.
- Don’t overcook the cauliflower: Overcooked cauliflower can become mushy and lose its texture. Roast it until it’s just tender, but still has texture.
- Brown the beef first: Before adding the cauliflower and tomatoes, brown the beef in the skillet and toss it with the spices to develop the best flavor.
- Serve with your favorite taco toppings: Serve it with your favorite taco toppings like fresh cilantro, chopped avocado, sour cream, and hot sauce. Jarred jalapeño rings add a great pop of flavor!
- Wrap it in tortillas: For those not watching their carbs, toast some flour or corn tortillas briefly in a dry skillet to serve with the Cauliflower Beef Taco Skillet.
- Make it ahead of time: This dish can be made ahead of time and reheated when you’re ready to eat. It’s a great option for busy weeknights or for meal prep.

Stir in the garlic, chili powder, cumin, oregano, smoked paprika, remaining ¾ teaspoon salt and ¼ teaspoon black pepper and the cayenne pepper (if using). Cook, stirring, for about 1 minute. Add the tomatoes and their juices and the roasted cauliflower. Increase the heat under the skillet as needed until you hear it bubbling. Then, immediately reduce the heat to LOW, cover, and simmer for 5 minutes, or until the cauliflower is tender.
