Ingredients

• 5 lbs Sweet potatoes, peeled and cubed
• 1 large loaf French bread, cut into 1-inch cubes
• 1 cup Unsalted butter, melted
• 1 large Yellow onion, diced
• 4 stalks Celery, chopped
• 3 cups Vegetable or chicken broth
• 2 large Eggs, lightly beaten
• 1/4 cup Fresh sage, finely chopped
• 1 tablespoon Fresh rosemary, minced
• 1 cup Chopped pecans
• 1/2 cup Brown sugar
• Salt and black pepper to taste

Directions

Step 1: Preparation

Start by boiling the cubed sweet potatoes in a large pot of salted water until they are just tender, about 10 to 12 minutes. Drain them thoroughly and set them aside to cool. While the potatoes boil, spread your bread cubes on a large baking sheet and toast them in a 350°F oven for 10 minutes until they feel dry and slightly crisp. In a medium skillet, sauté the diced onions and celery in two tablespoons of butter until they become translucent and fragrant.

Step 2: Assembly

In a very large mixing bowl, combine the toasted bread cubes, sautéed vegetables, and the cooked sweet potatoes. In a separate smaller bowl, whisk together the broth, beaten eggs, fresh sage, and rosemary. Pour this liquid mixture over the bread and potato blend. Gently fold everything together until the bread has absorbed the liquid but isn’t mushy. Grease a 9×13 inch baking dish (or two smaller dishes) and spread the mixture evenly. Cover the dish tightly with foil and refrigerate for up to two days.

Step 3: Baking

When you are ready to serve, preheat your oven to 375°F. Remove the casserole from the fridge and let it sit at room temperature for 20 minutes. In a small bowl, mix the chopped pecans, brown sugar, and the remaining melted butter. Sprinkle this topping over the casserole. Bake covered for 20 minutes, then remove the foil and bake for another 20 to 25 minutes until the top is golden brown and the center is hot. Serve immediately while bubbling.

Expert Tips for Perfect Best Make Ahead Thanksgiving Casseroles Sides 2026 Feed A Crowd

• Dry your bread: Use stale bread or toast it thoroughly. If the bread is too fresh, the casserole will turn soggy when you add the broth.
• Season in layers: Add a pinch of salt and pepper to the vegetables while sautéing and to the broth mixture to ensure every bite is flavorful.
• Room temperature: Always let your cold casserole sit on the counter for a bit before putting it in a hot oven to ensure even heating and prevent glass dishes from cracking.
• Herb infusion: Use fresh herbs rather than dried ones for the 2026 holiday season; the aromatic profile is significantly more vibrant.

Delicious Variations

• The Savory Sausage Twist: Add 1 lb of browned Italian sausage or breakfast sausage to the mix for a meatier, savory profile.
• Vegan Friendly: Swap the butter for olive oil or vegan butter, use vegetable broth, and replace the eggs with a flax-egg substitute.
• Extra Sweet: Add a layer of mini marshmallows on top during the last 5 minutes of baking for a nostalgic, gooey finish.
• The Cranberry Kick: Fold in one cup of dried cranberries during the assembly phase for a burst of tartness that cuts through the rich butter.

Frequently Asked Questions

How far in advance can I make this casserole?

You can fully assemble this casserole, cover it tightly, and keep it in the refrigerator for up to 48 hours before baking. This makes it perfect for prepping on Tuesday or Wednesday before Thanksgiving Thursday.

Can I freeze this dish before baking?

Yes, you can freeze the assembled casserole. Wrap it in a double layer of plastic wrap and then foil. It will stay fresh for up to three months. Thaw it completely in the refrigerator for 24 hours before you plan to bake it.

What is the best way to reheat leftovers?

Place individual portions in the microwave for 1-2 minutes, or put the entire dish back in a 350°F oven for about 15 minutes. Add a splash of broth if the bread seems a bit dry.

Can I use canned yams instead of fresh sweet potatoes?

You can use canned yams to save time, but be sure to drain them extremely well. Since canned yams are softer, fold them in very gently at the end so they don’t turn into a puree.

How do I scale this recipe for 25 people?

Simply double the ingredients and split the mixture into two large 9×13 baking dishes. You may need to rotate the dishes in your oven halfway through the baking time to ensure both brown evenly.
