How to Make Creamy Zucchini & Corn Mac and Cheese Bake

Preheat & Prep: Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish.
Cook Pasta: Boil pasta just until al dente (1–2 minutes shy of package directions). Drain and set aside.
Sauté Veggies: In a large skillet, melt 1 tablespoon butter over medium heat. Sauté zucchini and corn 3–4 minutes until just tender. Transfer to a plate.

Make Cheese Sauce: In the same skillet, melt remaining 2 tablespoons butter. Whisk in flour; cook 1 minute. Slowly whisk in milk, stirring until smooth and thickened, about 4–5 minutes.
Finish Sauce: Remove from heat. Whisk in Greek yogurt, cheddar, mozzarella, garlic powder, paprika, salt, and pepper. Stir until smooth and creamy.
Combine: Add cooked pasta, sautéed zucchini, and corn to the sauce. Toss to coat evenly.

Assemble: Spread mixture in prepared baking dish.
Top: Mix panko, Parmesan, olive oil, and a pinch of paprika. Sprinkle evenly over pasta.
Bake: Bake 20–25 minutes, until bubbling and golden brown. Broil 1–2 minutes for extra crisp topping if desired.

Garnish & Serve: Sprinkle with fresh herbs. Let cool slightly before serving.

What to Serve with Creamy Zucchini & Corn Mac and Cheese Bake

This dish stands on its own but pairs beautifully with:

Crisp green salad with lemon vinaigrette

Grilled or roasted chicken
Sautéed greens or steamed broccoli
Sliced tomatoes with salt and olive oil

Fresh fruit salad

Tips for Success

Don’t Overcook Pasta: Keep it slightly underdone so it doesn’t get mushy while baking.
Shred Cheese Fresh: Melts better and gives a creamier sauce.

Pat Zucchini Dry: Too much moisture can make the bake watery.
Broil for Crunch: A quick broil gives the top irresistible texture.
Rest Before Serving: Letting it sit for 5–10 minutes makes slicing easier.

Common Mistakes to Avoid

Sauce Too Thin: Let it thicken before adding cheese.
Soggy Veggies: Sauté zucchini briefly and don’t skip draining excess moisture.
Overbaking: Bake just until golden and bubbling for a creamy (not dry) mac.

Using Pre-Shredded Cheese: It can be coated in anti-caking agents—freshly grated melts best.

How to Store & Reheat

Store: Cool completely, cover, and refrigerate up to 4 days.
Freeze: Tightly wrap cooled bake and freeze up to 2 months. Thaw overnight in fridge.

Reheat: Cover with foil and bake at 350°F (175°C) until hot, or microwave in portions.
