Why You’ll Love This Easy Butternut Squash Casserole
This casserole is creamy yet light, rich but not heavy. It uses simple ingredients and turns them into a golden, bubbling bake that feels homemade every time. Plus, it fits both weekday mornings and special brunches. You can prep it early, bake it later, and still get that oven-fresh taste.
Key Ingredients You’ll Need
Core Ingredients for the Creamy Base
You’ll start with heavy cream (or coconut milk if you prefer dairy-free), crushed garlic, nutmeg, and fresh thyme. These infuse together to create a silky base that coats every slice of squash. Bay leaves bring subtle depth, and when the heat releases those aromas, it feels like instant fall in the kitchen.
Squash, Cheese, and Layering Essentials
Thinly sliced butternut squash is the heart of this dish. Mature white cheddar melts beautifully, forming that golden crust you’ll want to scoop right into. Butter helps crisp the edges and adds richness, balancing the natural sweetness of the squash.

How to Make This Easy Butternut Squash Casserole (Step-by-Step)
Step 1: Infuse the Cream with Herbs and Garlic
In a saucepan, combine 1 ¾ cups of heavy cream with 1 crushed garlic clove, a few thyme sprigs, 2 bay leaves, and ½ teaspoon of nutmeg. Heat gently until it begins to simmer, then remove from the heat. Let it rest for about 10 minutes so the herbs can release their flavor.
Step 2: Prep and Slice the Butternut Squash
Peel the butternut squash carefully, then slice it thin—about ⅛ inch thick. Consistent slices help it cook evenly and soak in the cream perfectly.
Step 3: Layer the Squash and Add Infused Cream
Grease your baking dish with butter. Layer half the squash, pour half the infused cream mixture over it, then repeat. This layering makes each bite creamy and balanced.
Step 4: Cover and Bake to Start the Cooking Process
Cover tightly with foil and bake in a preheated oven at 350°F for 30 minutes. This lets the squash soften gently without drying out.
Step 5: Add Cheese and Bake Until Golden and Bubbly
Remove the foil and top the casserole with one cup of grated mature cheddar. Bake uncovered for another 20–30 minutes until the cheese turns golden and the edges bubble.
Step 6: Cool Slightly and Serve Warm
Let it rest for 5–10 minutes before serving. The cream thickens slightly as it cools, making the texture smooth and custardy.
Helpful Ingredient Swaps and Variations
Dairy-Free and Vegan Alternatives
Swap the cream with coconut milk and the cheese with nutritional yeast. It still feels rich and cozy but completely plant-based.
Lower-Fat Options
Greek yogurt works in place of cream for a lighter texture. It adds a tang that pairs well with the sweetness of the squash.
Flavorful Cheese Substitutions
Try Gruyère or Gouda for a nutty twist. They melt into a velvety top layer that feels fancy but tastes familiar.
Vegetable Variations
Replace squash with thinly sliced sweet potatoes or pumpkin for a seasonal spin. The method stays the same, but the flavor shifts slightly toward sweet and earthy.
Serving Suggestions and Storage Tips
Serve warm with toast, fried eggs, or a light salad. For a heartier breakfast, pair it with something protein-packed like protein waffles or fluffy pancakes.
Store leftovers in an airtight container for up to three days. Reheat gently in the oven to keep the top crispy.
