👩🏻🍳 Here’s how to make it
Easy Vegetable Pasta Bake — step-by-step
- Preheat the oven: Heat to 200°C (390°F).
- Cook the pasta: Boil penne in salted water until al dente, drain and set aside.
- Sauté the aromatics: Warm olive oil in a skillet over medium heat. Cook chopped onion for 3–4 minutes until softened, then add minced garlic for 1–2 minutes.
- Cook the vegetables: Add chopped bell peppers, zucchini and carrot and cook 5–7 minutes until slightly tender.
- Make the sauce: Stir in canned chopped tomatoes, passata, tomato paste, dried oregano and basil. Season with salt and pepper and simmer 10–15 minutes until the sauce thickens.
- Combine: Toss the cooked pasta with the vegetable tomato sauce so it’s evenly coated.
- Assemble: Transfer the mixture to a large baking dish and top with shredded mozzarella and grated Parmesan.
- Bake: Bake for about 20 minutes until cheese is melted and golden. For an extra-browned top, broil 2–3 minutes at the end, watching carefully.
- Serve: Let rest a few minutes, garnish with fresh basil if using, and serve warm.
📖 Variations
- Vegetables: Swap in spinach, mushrooms, eggplant or other favourites.
- Cheese: Try cheddar, gouda or a cheese blend for different flavours.
- Gluten-free: Use gluten-free pasta to suit dietary needs.
- Protein: Add cooked chicken, sausage or tofu for a heartier bake.
- Spice: Red pepper flakes or a splash of hot sauce add heat.
💡 Chef’s Guide: Expert Tips
- Cheese blend: Mix a couple of melty cheeses (e.g., mozzarella with fontina or provolone) and a little Parmesan for depth.
- Undercook the pasta slightly so it finishes cooking in the oven and remains perfectly textured.
- Infused oil: Gently heat olive oil with crushed garlic and red pepper flakes before sautéing for extra flavour.
- Finish under the broiler for 2–3 minutes to achieve a bubbly, golden cheese crust — watch it closely to avoid burning.
🍯 Storing and reheating leftovers
- Fridge: Store cooled portions in an airtight container for 3–4 days.
- Freezer: Freeze the assembled (unbaked) dish for up to 2 months; thaw overnight before baking.
- Reheat: Reheat in a 180°C (350°F) oven covered with foil for 20–25 minutes, or microwave individual portions until hot.
❓Recipe FAQ’s
How can I make the sauce less acidic?
Add a pinch of sugar or a splash of cream to balance the acidity of the tomatoes.
What pasta works best for a bake?
Short, sturdy shapes like penne, rigatoni or fusilli hold sauce and texture well in bakes.
How do I boost dried herb flavour?
Rub dried herbs between your palms before adding them to release their oils, or add a fresh herb garnish at the end.
