Last updated on August 18th, 2025

Anyone else looking forward to pulling a bubbling, golden-brown casserole from the oven during the holiday season? The steam rising, the cheese pulling into perfect strings, and that moment when everyone at the table lets out a collective “mmm” – that’s what Christmas memories are made of. As someone who’s hosted more holiday gatherings than I can count, I’ve learned that casseroles are a host’s best friend. They’re make-ahead friendly, feed a crowd, and somehow manage to feel both special and comforting at the same time.

Today, I’m sharing my favorite Christmas casserole recipes that have earned permanent spots in my holiday rotation. These dishes aren’t just delicious, no no. They’re lifesavers when you’re juggling all the chaos of holiday hosting. You can assemble them the day before, and while your main course cooks, these beauties can be warming up in a second oven or taking turns in the main one.

Green Bean Casserole with Crispy Shallots (From Scratch!)

Forget the canned soup version – this from-scratch green bean casserole will make you feel like you’re tasting this classic for the first time.

The secret? Fresh green beans and homemade crispy shallots that’ll make you wonder why you ever used those canned onions.

This elevated version of the classic still brings the nostalgia factor, but with flavors that’ll impress even your foodie relatives. Plus, you can prep everything a day ahead and just add the crispy shallots right before baking.

Recipe

Prep Time: 30 minutes
Cook Time: 45 minutes
Total Time: 1 hour 15 minutes
Serves: 10-12

Ingredients

For the Crispy Shallots:

• 4 large shallots, thinly sliced
• 2 cups vegetable oil for frying
• 1/2 teaspoon salt

For the Casserole:

• 2 1/2 pounds fresh green beans, trimmed and cut into 2-inch pieces
• 3 tablespoons butter
• 1 pound mushrooms, sliced
• 4 cloves garlic, minced
• 3 tablespoons all-purpose flour
• 1 1/2 cups chicken broth
• 1 1/2 cups heavy cream
• 1 teaspoon fresh thyme leaves
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1/4 teaspoon nutmeg

How to Make

1. Make the crispy shallots first: Heat oil in a medium saucepan over medium heat. Test with one shallot ring – it should sizzle gently. Fry shallots in batches until golden brown, about 3-4 minutes. Drain on paper towels and sprinkle with salt.
2. Blanch green beans in boiling salted water for 5 minutes. Transfer to an ice bath, drain, and set aside.
3. Preheat oven to 375°F. Butter a 9×13 baking dish.
4. In a large skillet, melt butter over medium heat. Add mushrooms and cook until they release their liquid and it evaporates, about 8-10 minutes. Add garlic and cook 1 minute more.
5. Sprinkle flour over mushrooms and stir for 1 minute. Gradually whisk in broth and cream. Simmer until thickened, about 5 minutes. Add thyme, salt, pepper, and nutmeg.
6. Combine sauce with green beans and transfer to prepared baking dish. Can be covered and refrigerated at this point for up to 24 hours.
7. Bake for 30 minutes, add crispy shallots on top, and bake 10-15 minutes more until bubbly.

Tips and Tricks for Making Casseroles Ahead

Here are some more tips I have for you, to make your life easier:

• All these casseroles can be assembled up to 24 hours in advance and refrigerated.
• If baking straight from the fridge, add 10-15 minutes to the baking time.
• For the crumb toppings, keep them separate and add just before baking to maintain maximum crunch.
• Let refrigerated casseroles sit at room temperature for 30 minutes before baking for more even cooking.
• These casseroles freeze beautifully for up to 3 months – just thaw overnight in the refrigerator before baking.

Storage and Reheating Notes

Leftovers (if you have any!) will keep in an airtight container in the refrigerator for up to 4 days.

To reheat:

• Individual portions: Microwave for 2-3 minutes, stirring halfway through
• Whole casserole: Cover with foil and heat in a 350°F oven for 20-25 minutes until heated through

Cozy Christmas Casseroles

The holidays are hectic enough without having to worry about what to feed everyone. These casseroles are my secret weapon for stress-free entertaining. They’re crowd-pleasers, I can assure you!

And really, one of the best things about these recipes is their flexibility – feel free to adapt them to your family’s tastes. Add different vegetables, swap out cheeses, or adjust the seasonings.

Happy holidays and happy cooking!
