Preheat and prep: Heat the oven to 400°F (200°C). Lightly grease 4–6 oven-safe bowls, ramekins, or a medium casserole dish. If you’re using veggies that release water (like mushrooms), slice them now.
Toast the spices: In a large skillet, warm 1 tablespoon olive oil over medium heat.
Add fennel seeds and red pepper flakes. Cook 30 seconds until fragrant. This wakes up the spices and gives the chicken a “pizzeria sausage” vibe.
Sauté aromatics: Add the diced onion and a pinch of salt.
Cook 3–4 minutes until softened. Stir in the garlic and tomato paste; cook 1 minute to caramelize slightly.
Brown the chicken: Add the ground chicken, breaking it up with a spatula. Season with Italian seasoning, 1 teaspoon salt, and several grinds of black pepper.
Cook 5–7 minutes until just cooked through. Don’t overcook—chicken will finish in the oven.
Simmer with sauce: Pour in 1 cup crushed tomatoes or pizza sauce and stir to coat the chicken. Simmer 2–3 minutes.
Taste and adjust salt, pepper, and heat. You want a well-seasoned, slightly saucy base.
Pre-cook watery toppings: In a separate skillet, quickly sauté mushrooms, peppers, or spinach with a little oil and salt until just softened. This prevents watery bowls and keeps flavors concentrated.
Assemble the bowls: Spoon a layer of the chicken mixture into each bowl.
Add a spoonful of sauce if you like it extra saucy. Top with your chosen veggies and meats. Sprinkle mozzarella generously and finish with Parmesan.
Bake: Place bowls on a sheet pan for easy handling.
Bake 10–15 minutes until the cheese is melted and bubbling. For a golden top, switch to broil for 1–2 minutes. Watch closely.
Finish and serve: Let bowls rest 5 minutes so they set slightly.
Garnish with torn basil or chopped parsley. Add a crack of black pepper and a drizzle of olive oil if you want a glossy finish.
