3 Tips for Making this Zucchini Alfredo Bake

Here you’ll find 3 pro tips to help you make the most out of this zucchini alfredo bake recipe.

  • Slice the veggies as evenly as possible. To promote even cooking, slice the zucchini into similar-sized rings and slice the mushrooms into similar-sized pieces.
  • Cook the veggies until golden for an extra smokey flavor. Baking/grilling the zucchini and sautéing the mushrooms until golden brown will add such a nice spark of flavor to your bake. It’s worth the extra couple of steps!
  • Serve the zucchini alfredo bake immediately out of the oven. This bake is best served right out of the oven when the cheese is melty and the sauce is bubbly.

Hot Tip: Garnish your zucchini bake with herbs to elevate the flavor of the dish that much more. Some fresh parsley or basil works great!

Ideas for Serving Your Bake

Serve this zucchini alfredo bake as a tasty veggie side dish to just about any protein. It goes great with air fryer chicken breast, air fryer shrimp, or a cast-iron ribeye. Or, boil your favorite pasta until al dente and toss it directly into the bake. If you’re feeling ambitious, make our easy homemade pasta!

Low-Carb/Keto Dinner Hack: Watching your carbohydrates? Instead of slicing the zucchini into rings, use a spiralizer to make zucchini noodles, aka “zoodles”, or a mandolin slicer to make zucchini ribbons to have yourself a guilt-free zucchini-style ziti!

How to Store Your Zucchini Alfredo Bake

Whether you have a couple of servings leftover to store in the fridge or an entire bake you’d like to freeze, find all the best storage tips right here.

  • Refrigerator: To keep your zucchini alfredo bake leftovers on hand for up to 5 days, store them in an airtight container in the fridge. This will keep the bake from turning soggy faster.
  • Freezer: It’s not recommended to freeze this bake, as the cooked veggies don’t thaw particularly well. The same goes for the alfredo sauce – upon reheating, the cream will separate.


What other veggies go great in this alfredo bake besides mushrooms?

If you’re not a fan of mushrooms, swap them out for sautéed broccoli or cauliflower.

How long does it take to broil or grill the zucchini?

There’s no exact science to how long it takes to broil or grill the zucchini. Once they turn golden brown, remove them from heat. Typically, this takes a couple of minutes on each side.

There are so many different cheeses that would work great in this recipe. Shredded parmesan, herbed goat cheese, cream cheese, and even crumbled feta are all wonderful options.

How do you ensure the zucchini doesn’t turn soggy?

Add a couple of dashes of red pepper flakes or hot sauce to the bake to turn the heat level up.
