Equipment For Veggie Spaghetti Casseroles
To make these delicious Veggie Spaghetti Casseroles, you’ll need:
- 4 mini oven-safe casserole dishes (ceramic or glass, approx. 10–12 cm diameter) — ideal for individual portions.
- Medium saucepan — for cooking the pasta and vegetables.
- High-speed blender or food processor — to blend the cooked vegetables into a smooth, thick sauce.
Alternative: Use a hand blender directly in the saucepan if you don’t have a countertop blender. - Mixing bowl — to combine the pasta and sauce before assembling the casseroles.
- Spoon or ladle — for portioning into dishes.
- Cheese grater — for grating fresh cheese topping.
- Measuring cups & spoons — to ensure ingredient accuracy.
- Air fryer-safe ramekins (optional) — if baking in an air fryer instead of a traditional oven.
Alternative if you don’t have mini casserole dishes:
Use one medium-sized ovenproof dish instead. You may need to increase the baking time by 5–8 minutes. Once baked, you can scoop or cut into individual portions, or even slice into squares for easy lunchbox packing.
Instructions
- Cook the spaghetti
- Bring a large pot of salted water to a boil. Add the spaghetti and cook according to package instructions until al dente. Drain and set aside.
- Prepare the vegetable sauce
- Heat olive oil in a large skillet over medium heat. Add onion and garlic, sauté for 2–3 minutes until softened.
- Add carrot, bell pepper, zucchini, and spinach. Cook for 5–6 minutes until the vegetables soften.
- Stir in chopped tomatoes, oregano, and basil. Season with salt and pepper. Simmer for 10 minutes.
- Blend the sauce
- Use an immersion blender to blend the vegetables into a thick, smooth sauce. If you don’t have one, transfer the mixture to a blender in batches and blend carefully. Return to the skillet and keep warm.
- Assemble the casseroles
- Preheat the oven to 180°C (350°F).
- Divide the cooked spaghetti among four mini oven-safe casserole dishes. Pour the vegetable sauce evenly over each dish and stir gently to coat.
- Add the topping
- Sprinkle each casserole with mozzarella cheese and breadcrumbs. Drizzle lightly with olive oil for extra crispiness.
- Bake or air fry
- Oven: Bake for 12–15 minutes, until the topping is golden brown.
- Air fryer: Place mini casseroles in the basket and cook at 180°C (350°F) for 8–10 minutes.
