Flavor notes and quick swaps

This recipe leans on classic Caprese ingredients. If you prefer a creamier texture, the 1/4 cup half and half gives a gentle silkiness without overpowering the tomatoes. The crushed red pepper is optional — start with 1/4 teaspoon if you like a small bite and up it to 1/2 teaspoon if you want more heat.

If you want a dairy-free version, substitute the Parmesan and mozzarella with your preferred dairy-free shreds and nutritional yeast, and swap half and half for a neutral-tasting plant milk. The rest of the ingredients remain the same.

Rewritten step-by-step directions

Follow these steps in the same overall order as the original method. Measurements are unchanged and ingredient names match the list above.

1. Preheat your oven to 375°F (190°C). Lightly grease your casserole dish so the mixture won’t stick.
2. Rinse the 1 cup uncooked quinoa under cold water and drain. Place the rinsed quinoa in a medium saucepan and add 2 cups chicken broth. Bring to a boil over medium-high heat, then reduce the heat to low, cover, and simmer for about 12–15 minutes, or until the quinoa has absorbed the liquid and is tender. Once cooked, fluff with a fork and set aside.
3. While the quinoa cooks, combine the sauce ingredients in a mixing bowl: stir together 2 cups crushed tomatoes, 2 tablespoons tomato paste, 1 tablespoon balsamic vinegar, 1/4 cup half and half, and 1/4 to 1/2 teaspoon crushed red pepper if using. Season the mixture with salt and pepper to taste. Whisk until the tomato paste is fully incorporated and the sauce is smooth.
4. Into a large bowl, add the cooked quinoa, 3 cups diced rotisserie chicken (or other cooked chicken), and the prepared tomato-balsamic sauce. Mix gently until the quinoa and chicken are evenly coated with the sauce.
5. Stir in 1/4 cup grated Parmesan cheese and 1/2 cup of the shredded mozzarella cheese (reserve the remaining 1/2 cup for topping). Taste and adjust seasoning with more salt and pepper if needed.
6. Pour the quinoa and chicken mixture into your greased casserole dish, spreading it into an even layer. Scatter 1 cup halved grape tomatoes evenly across the top of the casserole.
7. Sprinkle the reserved 1/2 cup shredded mozzarella cheese over the tomatoes so it melts and forms a light golden layer while baking.
8. Cover the casserole dish loosely with aluminum foil and bake in the preheated oven for 20 minutes. After 20 minutes, remove the foil and continue baking for an additional 10–15 minutes, or until the cheese on top is bubbly and lightly golden and the casserole is heated through.
9. Remove the casserole from the oven and let it rest for 5 minutes. This short rest helps the casserole set and makes serving easier.
10. Garnish the baked casserole with a handful of chopped fresh basil just before serving. Cut into portions and enjoy warm.

Serving suggestions

• Serve slices straight from the casserole dish with a simple mixed green salad dressed in lemon and olive oil to add a crisp contrast.
• Leftovers are great reheated in the oven at 350°F for 10–15 minutes or warmed in the microwave for single portions.
• For a heartier meal, pair a portion with roasted vegetables or garlic green beans.

Meal prep and storage

This casserole holds up well for meal prep. Store cooled portions in airtight containers in the refrigerator for up to 4 days. Freeze individual portions for up to 3 months; thaw overnight in the refrigerator before reheating.

Notes and tips from the kitchen

• Using pre-cooked chicken cuts the hands-on time dramatically. Rotisserie chicken is a great shortcut, but any leftover roasted or poached chicken will work.
• Rinsing quinoa removes the naturally bitter coating and helps it cook up light and fluffy.
• If your crushed tomatoes are very watery, you can simmer them briefly with the tomato paste before combining with the half and half to concentrate the flavor.
• When chopping the basil, use a sharp knife and avoid bruising the leaves too much so they keep their bright flavor when added fresh at the end.

Frequently asked questions

Can I make this vegetarian? Yes. Omit the chicken and increase the quinoa to 1 1/2 cups and the broth slightly if needed, or add a can of drained beans for extra protein. Adjust seasonings to taste.

Can I skip the cheese? You can reduce or omit the cheeses, but they contribute to the characteristic Caprese-style creaminess. Consider using a dairy-free cheese if avoiding dairy.

Is the quinoa fully cooked before baking? Yes. Cook the quinoa first so it absorbs its liquid and reaches tender texture. The short time in the oven mainly melts cheese and brings flavors together rather than cooking raw quinoa.
