20-Minute One-Pan Mexican Cauliflower Rice & Beef Skillet

Ingredients

For the Sizzling Skillet:

• 1.5 lbs 100% grass-fed ground beef (85/15 blend) or ground bison / turkey
• 1 tbsp unrefined avocado oil or grass-fed beef tallow
• 4 cups fresh riced cauliflower (fresh cauliflower maintains crisp texture best)
• 1 medium red bell pepper, diced
• 1 medium yellow onion, diced
• 4 cloves garlic, minced
• 1 can (14.5 oz) organic fire-roasted diced tomatoes, lightly drained
• 2 tbsp organic tomato paste
• 1.5 tbsp chili powder (mild ancho chili blend)
• 1 tbsp ground cumin
• 1 tsp smoked paprika
• 1 tsp dried Mexican oregano
• 0.5 tsp garlic powder and 0.5 tsp onion powder
• 1.5 tsp coarse Celtic sea salt
• 0.5 tsp freshly ground black pepper

For the Fresh Primal Toppings:

• 1 large ripe Hass avocado, diced or sliced
• 0.33 cup chopped fresh cilantro
• 1 fresh jalapeño, thinly sliced
• 1 organic lime, cut into wedges (for finishing spritz)

Step-by-Step Instructions

1. Brown the Ground Beef: Heat 1 tbsp avocado oil in a wide 12-inch cast-iron skillet over medium-high heat. Add ground beef, breaking it into small crumbles with a wooden spoon. Cook for 5 to 6 minutes until browned and caramelized at the edges. (Drain excess fat if needed, leaving 1 tbsp in the pan).
2. Sauté Mirepoix & Aromatics: Push the beef to one side of the skillet. Add diced bell pepper, diced onion, and minced garlic to the open space. Sauté for 3 to 4 minutes until the vegetables begin to soften and become fragrant.
3. Bloom the Mexican Spices: Stir in tomato paste, chili powder, cumin, smoked paprika, Mexican oregano, garlic powder, onion powder, sea salt, and black pepper. Stir into the beef and vegetables for 60 seconds to toast the aromatic spices.
4. Add Fire-Roasted Tomatoes & Cauliflower Rice: Add the drained fire-roasted diced tomatoes and 4 cups of riced cauliflower to the skillet. Toss thoroughly with a spatula to combine all ingredients into the flavorful spiced beef drippings.
5. High-Heat Sauté (Prevent Soggy Rice): Cook uncovered over medium-high heat for 4 to 5 minutes, stirring frequently. (Cooking uncovered on high heat evaporates natural cauliflower moisture rapidly, keeping the rice tender-crisp rather than watery).
6. Finish with Fresh Lime: Remove the skillet from heat. Squeeze the juice of half a fresh lime across the sizzling skillet and toss once more.
7. Garnish & Serve: Top the warm skillet with diced ripe avocado, sliced fresh jalapeños, chopped cilantro, and extra lime wedges. Serve straight from the skillet into bowls.

Chef's Paleo Nutritional Science

Grass-fed beef provides highly bioavailable zinc, Vitamin B12, and conjugated linoleic acid (CLA), supporting testosterone synthesis and metabolic rate. Cruciferous cauliflower supplies indole-3-carbinol and glucoraphanin, which promote cellular Phase II antioxidant defense without triggering grain-associated intestinal permeability.
