What You’ll Need

• 2 boneless, skinless chicken breasts, cut into bite-sized pieces
• 2 tablespoons olive oil
• Salt and pepper, to taste
• 1/2 teaspoon garlic powder
• 1/2 teaspoon paprika
• 1 medium head of cauliflower, grated into rice-sized bits or 4 cups pre-made cauliflower rice
• 2 tablespoons olive oil
• 1/4 cup onion, diced
• 2 garlic cloves, minced
• Salt and pepper, to taste
• 1 cup fresh basil leaves
• 1/4 cup grated Parmesan cheese
• 1/4 cup pine nuts (or walnuts if you prefer)
• 2 garlic cloves
• 1/4 cup olive oil
• Salt and pepper, to taste

Step-by-Step Directions

1. Cut 2 boneless, skinless chicken breasts into bite-sized pieces.
2. Grate 1 medium head cauliflower into rice-sized bits or measure 4 cups pre-made cauliflower rice.
3. Mince 4 garlic cloves and dice 1/4 cup onion.
4. Warm 2 tablespoons olive oil in a large skillet over medium-high heat.
5. Season the diced chicken with salt, pepper, 1/2 teaspoon garlic powder, and 1/2 teaspoon paprika.
6. Cook the chicken in the hot skillet, stirring occasionally, until golden and cooked through, about 6–8 minutes; remove and set aside to rest for 1 minute.
7. Add 2 more tablespoons olive oil to the same pan.
8. Cook the diced onion 2–3 minutes until soft, then add minced garlic and cook 30 seconds until fragrant.
9. Add the cauliflower rice to the pan, season with salt and pepper, and cook 5–7 minutes, stirring occasionally, until tender but still slightly firm.
10. Make the pesto: in a food processor combine basil, Parmesan, pine nuts, and garlic; pulse until finely chopped, then with the machine running slowly pour in olive oil until smooth; season with salt and pepper (or measure 2–3 tablespoons if using store-bought pesto).
11. Return the cooked chicken to the skillet with the cauliflower rice and stir to combine.

12. Add 2–3 tablespoons pesto and toss to coat evenly; cook 2–3 minutes more to meld flavors, then taste and adjust seasoning or add more pesto if needed.

Pro Tips and Serving Ideas

• Don’t cook the cauliflower rice too long—aim for tender with just a bit of bite to avoid a mushy mess.
• Season the cauliflower rice well; salt, pepper, and even a squeeze of lemon juice brighten everything up beautifully.
• Let cooked chicken rest off the heat for a minute before mixing it in. This helps keep it juicy and tender.
• Try toasting your pine nuts or walnuts briefly in a dry pan before blending pesto for an extra pop of flavor.
• If your pesto feels too thick, thin it out with a bit more olive oil or a splash of water until it spreads easily.
• Use a hot pan and don’t add too much oil when cooking cauliflower rice so it sautés instead of steams—this keeps it from turning soggy.

This dish stands perfectly on its own, but you can also serve it alongside a simple salad topped with lemon vinaigrette for a fresh crunch. Garlic bread or roasted asparagus are great sides, too, if you’re craving a heartier meal.

Variations and Substitutions

• Swap the protein: shrimp, tofu, or even thinly sliced steak all work great here—just adjust cooking times as needed.
• Make it creamy by stirring in a splash of heavy cream or full-fat coconut milk right at the end for smooth richness.
• Like heat? Add red pepper flakes or finely chopped jalapeño to your pesto for a spicy kick.
• Change up the nuts in your pesto: toasted walnuts or almonds add a lovely different flavor profile.
• Boost the veggies by folding in baby spinach, halved cherry tomatoes, or sautéed bell peppers for color and extra nutrition.
• Going dairy-free? Skip the Parmesan or swap it for a dairy-free substitute in your pesto.

• Switch the chicken for shrimp or tofu for a twist.
• Add a handful of spinach or kale while cooking cauliflower rice for extra greens.
• Try a sun-dried tomato pesto for a different flavor profile.
• Mix in some sautéed mushrooms or zucchini for more veggies.
• Use almond or cashew nuts in your pesto instead of pine nuts for a nutty flair.

Storing, Freezing, and Reheating

Keep any leftover pesto chicken cauliflower rice in an airtight container in your fridge for up to 3 to 4 days. For longer storage, freeze chicken and cauliflower rice separately so they keep their best texture—freeze for up to 2 months, then thaw overnight in the fridge before reheating.

To reheat, warm gently in a skillet over medium heat, adding a splash of water or broth if things seem dry. You can also pop individual servings in the microwave, covered, in 30-second bursts until hot.

Once cooked, this meal keeps nicely in the fridge for 3–4 days. Store it in airtight containers to retain freshness. For longer-lasting meals, freeze chicken and cauliflower rice in separate containers. This way, you can thaw only what you need and keep flavors fresh.

This recipe is fantastic for making ahead. Cook everything up to 2 days in advance, then cool and store in the fridge. When you’re ready, just reheat it on the stove or microwave and enjoy a quick, delicious meal without the hassle.
