• 2 tablespoons butter
• 2 tablespoons all-purpose flour

• Salt and pepper, to taste

For Baking:

• ½ cup mozzarella (extra, for topping)
• ¼ cup breadcrumbs (optional, for crunch)
• 1 tablespoon olive oil (to drizzle on top)

Simple Cooking Directions

1. Roast vegetables until tender and slightly caramelized.
2. Cook pasta until al dente.
3. Make the creamy Alfredo sauce.
4. Combine roasted veggies, pasta, and sauce.
5. Transfer to a baking dish, top with cheese, and bake until golden and bubbly.

Step-by-Step Preparation Method

Step 1: Roast the Vegetables

1. Preheat oven to 425°F (220°C).
2. Place zucchini, peppers, onion, and broccoli on a baking sheet.
3. Drizzle with olive oil, sprinkle salt, pepper, and Italian seasoning, then toss to coat.
4. Roast for 20–25 minutes, stirring halfway, until tender and lightly browned.

Step 2: Cook the Pasta

While veggies roast, cook pasta in salted boiling water until al dente (slightly firm).
Drain, toss with a little olive oil to prevent sticking, and set aside.

Step 3: Prepare the Alfredo Sauce

1. In a saucepan over medium heat, melt butter and add minced garlic.
2. Stir in flour and whisk for 1 minute to form a roux.
3. Slowly pour in milk and cream while whisking continuously until smooth.
4. Cook until slightly thickened (about 4–5 minutes).
5. Stir in Parmesan and mozzarella cheeses until melted and creamy.
6. Season with salt, pepper, and nutmeg. Remove from heat.

Step 4: Combine Everything

In a large mixing bowl, combine pasta, roasted vegetables, and Alfredo sauce. Toss gently to coat evenly.

Step 5: Assemble the Bake

1. Transfer mixture to a greased 9×13-inch baking dish.
2. Sprinkle extra mozzarella and breadcrumbs over the top.
3. Drizzle a little olive oil for extra crispness.

Step 6: Bake

Bake at 375°F (190°C) for 20–25 minutes, until golden and bubbly on top.

Step 7: Serve

Let cool slightly before serving so the sauce sets beautifully.

How to Serve

Serve your Roasted Veggie Alfredo Pasta Bake warm, garnished with:

• Fresh parsley or basil
• Extra grated Parmesan
• A side of garlic bread or green salad

This dish pairs wonderfully with a light soup, iced tea, or white wine like Chardonnay or Pinot Grigio.

Additional Recipe Tips

• Don’t overcook pasta: It will continue to cook in the oven.
• Use fresh Parmesan: Pre-grated cheese doesn’t melt as smoothly.
• Balance your veggies: Choose a mix of colors and textures for best results.
• Add protein if desired: Grilled chicken, shrimp, or tofu make great additions.
• For a richer sauce: Add a tablespoon of cream cheese to the Alfredo.

Recipe Variations

1. Chicken Alfredo Pasta Bake: Add cooked chicken breast or rotisserie chicken.
2. Spicy Kick: Add crushed red pepper flakes to the sauce.
3. Extra Veggie Version: Add spinach, mushrooms, or roasted cherry tomatoes.
4. Vegan Option: Use plant-based cream, vegan butter, and vegan cheese.
5. Gluten-Free: Use gluten-free pasta and flour for the roux.

Freezing and Storage

Refrigeration:

• Store leftovers in an airtight container for up to 4 days.
• Reheat in the oven at 350°F (175°C) for 15 minutes, or microwave individual servings.

Freezing:

1. Assemble the pasta bake (without baking it).
2. Cover tightly with foil and freeze for up to 2 months.
3. To bake from frozen, thaw overnight in the fridge and bake for 30–35 minutes until bubbly.

Special Equipment Needed

Frequently Asked Questions (FAQ)

Q1: Can I use store-bought Alfredo sauce?
Yes! Use about 2 cups of your favorite Alfredo sauce if you’re short on time.

Q2: My sauce turned grainy — why?
That happens if the cheese is added too quickly or the sauce overheats. Add cheese off-heat and whisk until smooth.

Q3: Can I use frozen vegetables instead of fresh?
Yes, but roast them a bit longer to remove excess moisture before mixing into the pasta.

Q4: Can I make this ahead of time?
Absolutely. Assemble the dish, cover, and refrigerate up to 24 hours before baking.

Q5: How do I make it lighter?
Use milk instead of heavy cream and reduce cheese slightly — it’ll still be creamy and delicious!
