Why I Love This Recipe

Minestrone has always been one of my favorite soups—it’s full of texture, veggies, and Italian flavor. But let’s be honest: sometimes I want something that I can bake once, serve hot, and enjoy leftovers of later. That’s why this casserole version is genius. You still get the hearty goodness of pasta, tomato, and herbs, but now with a bubbly cheese top and a cozy oven-baked vibe.

Plus, it’s totally customizable—use whatever veggies or pasta you have on hand.


📋 Ingredients

  • 2 cups cooked pasta (any short shape like penne, rotini, or shells)
  • 1 can diced tomatoes (14.5 oz, undrained)
  • 1 cup mixed vegetables (frozen carrots, peas, corn, or a fresh mix)
  • 2 tbsp olive oil
  • 1 tbsp Italian seasoning
  • Salt and pepper, to taste
  • 1 cup shredded mozzarella cheese

🥦 Ingredient Tips & Swaps

  • Pasta: Whole wheat or gluten-free pasta works great too.
  • Veggie upgrades: Add sautéed zucchini, spinach, or bell peppers for extra nutrients.
  • Protein idea: Toss in canned white beans or chickpeas for added heartiness.
  • Cheese swap: Try shredded provolone or a sprinkle of Parmesan for extra flavor.

👨‍🍳 Instructions

  1. Preheat oven to 375°F (190°C).
  2. Mix the base: In a large bowl, combine cooked pasta, diced tomatoes (with juice), mixed vegetables, olive oil, Italian seasoning, salt, and pepper. Stir well.
  3. Layer & top: Pour mixture into a greased casserole dish. Top evenly with shredded mozzarella.
  4. Bake: Place in the oven and bake for 20–25 minutes, or until bubbly and cheese is lightly golden.
  5. Serve hot: Let cool slightly and serve warm with crusty bread or a side salad.

🔥 Tips for Casserole Success

  • Cook pasta just al dente: It will soften further while baking.
  • Don’t skip the olive oil: It helps bind the mix and enhances the roasted flavor.
  • Broil for golden cheese: Want a bubbly top? Broil for 2 minutes at the end, watching closely.
