Prep the base. If using a whole cauliflower, pulse florets in a food processor to make rice-sized pieces. Pat dry with paper towels to remove moisture.
Set aside.
Season the chicken. In a bowl, toss chicken with 1 tablespoon olive oil, smoked paprika, oregano, 1/2 teaspoon salt, and 1/4 teaspoon black pepper.
Sear the chicken. Heat a large skillet over medium-high. Add 1 tablespoon olive oil and 1 tablespoon butter. Once hot, add chicken in a single layer.
Cook 5–7 minutes, stirring once or twice, until browned and cooked through. Transfer to a plate.
Sauté the aromatics. Lower heat to medium. Add remaining 1 tablespoon butter and the minced garlic.
Stir 30–45 seconds until fragrant—don’t let it burn.
Build the sauce. Pour in chicken broth and lemon juice. Scrape up browned bits. Stir in heavy cream, lemon zest, and red pepper flakes.
Simmer 2–3 minutes until slightly thickened. Season with salt and pepper to taste.
Add the veggies. Stir in zucchini and bell pepper. Cook 2–3 minutes until just tender but still crisp.
Add spinach and wilt for 30 seconds.
Return the chicken. Add the chicken and any juices back to the skillet. Toss to coat in the sauce. Simmer 1 minute to heat through.
Adjust seasoning if needed.
Cook the cauliflower rice. In another skillet, heat a drizzle of olive oil over medium-high. Add cauliflower rice with a pinch of salt and pepper. Cook 4–5 minutes, stirring, until hot and just tender.
For extra flavor, splash in a tablespoon of the garlic sauce from the chicken pan.
Assemble the bowls. Spoon cauliflower rice into bowls. Top with garlic chicken and veggies. Garnish with parsley.
Add avocado, almonds, or Parmesan if you like.
