This cozy vegetarian pasta bake with roasted cauliflower, carrots, and onions smothered in tomato basil sauce and gooey mozzarella makes the perfect comfort meal for chilly nights.
On a rimmed baking sheet, toss cauliflower, carrots, and onions with olive oil, garlic powder, salt, and pepper. Spread in an even layer and roast for 35 to 40 minutes until fork tender.
While veggies roast, cook orzo in boiling salted water for 7 to 8 minutes until al dente. Drain and rinse. Set aside.
Heat a tablespoon of olive oil in an oven-safe skillet over medium-high heat. Add minced garlic and cook for 1 minute.
Add roasted vegetables, cooked orzo, and tomato basil sauce to the skillet. Stir to combine.
Add half of the shredded mozzarella and stir gently. Top with remaining mozzarella.
Cover and cook for 5 minutes until cheese on top is melted and gooey.
Uncover and garnish with red pepper flakes. Serve warm.
