- yellow onion & fresh garlic – perfect for getting the flavors started!
- all-purpose flour – thickening agent for the sauce in this easy recipe. Option to sub with gluten-free flour.

How To Make Delicata Squash au Gratin
The first steps to making this easy au gratin recipe are to prep the fresh squash by cutting them in half (lengthwise), scoop out the insides, and then use a sharp knife to slice them into half moons. Toss these squash slices with some olive oil, season with salt and pepper, and then place them in a baking dish. Bake at 425 degrees F for 15-20 minutes.
While the squash is roasting, you can start the cheesy mixture that you will pour on top. Start by bringing a large skillet to a medium high heat, add the butter to melt, and then sauté the garlic and onion.
Now add the flour to the hot pan.
And whisk to combine and create a thick paste around the onions and garlic.
Then gradually pour in your creamer of choice and broth, while continuously whisking. This will create a smooth and creamy sauce. Remove the pan from the heat and add in the parmesan cheese and a half cup of the shredded gruyere cheese. Mix to melt the cheese.
After the squash is finished roasting, remove from the oven and pour this cheesy sauce over the top. Finally, sprinkle the rest of the gruyere cheese over the top and return to the oven for 8-10 minutes. For best results, finish the baking process with 1-3 minutes under the broiler. This will give the top of the dish a nice, golden brown color.
Best Ways To Serve Delicata Squash au Gratin
This decadent side dish can be served with just about anything! We love adding it to our holiday menu and serve it alongside a traditional turkey and all the other traditional side dishes. Or you can add it to your next family gathering and serve with a roasted chicken and mashed potatoes!
Yes! After delicata squash is cooked, the skin becomes soft and completely edible. If you prefer to not eat the skin, you can use a peeler or sharp knife to remove before cooking. Up to you, but we like to keep it simple and enjoy the added nutrients!
Absolutely! We love the creaminess and flavor that comes along with gruyere and parmesan cheese, but you could also use mozzarella cheese or a white cheddar cheese.

Delicata Squash au Gratin is a decadent, delicious holiday side dish that is perfect for Easter, Thanksgiving, or Christmas!
- 2–3 medium delicata squash, halved and cut into 1/2 inch slices
- 1 tablespoon extra virgin olive oil, more if needed
- 1 1/2 teaspoon kosher salt, divided
- 1/8 teaspoon ground black pepper
- 2 tablespoons butter
- 1/4 cup sweet yellow onion, minced
- 1 teaspoon garlic, minced
- 2 1/2 tablespoons all-purpose flour (sub 1-to-1 gluten-free flour)
- 3/4 cup Nutpods original unsweetened creamer OR heavy cream
- 1/2 cup chicken broth
- 2 tablespoons parmesan cheese, freshly grated
- 1 cup gruyere cheese, freshly grated
- Preheat oven to 425 degrees F.
- Prepare delicata squash by remove the ends, slicing in half lengthwise and then cutting into 1/2 inch thick half moons. Place in a bowl and toss with olive oil. Season with kosher salt and ground black pepper. Place in rows in an 8×12 baking dish. Place in oven, middle rack, for 15-20 minutes.
- Meanwhile, bring a cast iron skillet to medium-high heat. Add butter and let melt; swirl to coat the pan. Add onion and garlic. Move around until garlic becomes fragrant and onion starts to soften, approx. 1-2 minutes.
- Add flour and whisk to combine with butter to create a paste (aka a roux). Continue whisking while adding the creamer and then broth, approx. 1/4 cup at a time. Continue whisking and letting it simmer until consistency is thick and creamy. If it feels too thick, add another splash or two of broth and stir.
- Remove from heat and add parmesan and 1/2 cup of the Gruyere cheese. Stir until cheese has melted. Taste and add any salt or pepper, as desired.
- Pour creamy sauce over roasted delicata squash (after it’s done baking) and then sprinkle with remaining 1/2 cup of Gruyere. Return casserole dish to the oven, middle rack and uncovered, for 8-10 minutes. Then move to the broiler for 1-3 minutes (I would recommend leaving the door open so you can watch carefully) or until sauce is bubbly and starting to turn golden brown.
- Remove and let cool 10 minutes before serving.
- *Creamer: I love using Nutpods (ensure it is unsweetened and unflavored) – you can’t tell the difference and it just lightens up this otherwise heavier (but delicious) holiday side dish! Use what works best for you, but I highly recommend you try it!
- Storage: store leftovers in an airtight container in the refrigerator for up to 5 days.
