A Holiday Classic, Made from Scratch

Green bean casserole is a holiday favorite for a reason: creamy sauce, tender vegetables, and a crisp topping make a combination everyone recognizes. Chef Brian Duffy brings fresh ingredients and thoughtful technique to this green bean casserole recipe, creating a side dish that feels both comforting and special. Instead of canned soup and packaged onions, his version uses a homemade mushroom sauce and freshly fried shallots.

Fresh Beans and a Rich Mushroom Sauce

For a homemade green bean casserole with satisfying texture, Brian starts by blanching haricots verts briefly, then cooling and drying them thoroughly. This helps them stay pleasantly tender through their final bake. Cremini mushrooms are browned in butter before onion and garlic join the pan. Flour, stock, milk, and cream turn those savory ingredients into a silky sauce. A finishing spoonful of Würzpott Mamma Limone! brings a bright contrast to the richness, while grated Parmesan rounds out the flavor.

Crispy Shallots Make the Difference

The topping is where this green bean casserole from scratch really stands apart. Thinly sliced shallots are coated in flour and Würzpott Smoky Cowboy, then fried until golden. Their delicate crunch and smoky seasoning balance the creamy casserole beautifully. Brian adds some shallots before baking and saves the rest for serving, so each portion gets a freshly crisp finish.

Made for Holiday Gatherings

This generous casserole serves 10 to 12, making it a natural fit for Thanksgiving, Christmas, or a Sunday family dinner. It pairs beautifully with roasted turkey, ham, or chicken. It also offers useful flexibility when the oven is busy: the beans and sauce can be prepared ahead, then combined and baked on the day of your gathering. Keep the crispy shallots stored separately until needed.

A New Favorite for Your Table

With fresh beans, deeply savory mushrooms, and two distinctive seasoning touches, Chef Brian Duffy transforms a familiar side dish into something guests will remember. Würzpott Mamma Limone! adds brightness to the sauce, and Würzpott Smoky Cowboy gives the shallots a delicious smoky edge. It is a homemade holiday classic worth making again.

Ingredients

Green Beans
3 lb haricots verts (French green beans), trimmed and cut into 2-inch pieces
2 Tbsp kosher salt, (for blanching water)
Mushroom Sauce
4 Tbsp unsalted butter
1 lb cremini mushrooms, sliced
1 small onion, finely diced
4 cloves garlic, minced
¼ cup all-purpose flour
1½ cups low-sodium chicken or vegetable stock
1½ cups whole milk
½ cup heavy cream
1 Tbsp Würzpott Mamma Limone!
½ cup Parmesan, grated
Crispy Shallots
6 large shallots, thinly sliced into rings
½ cup all-purpose flour
2 tsp Würzpott Smoky Cowboy
1½ cups neutral oil, (for frying)

Directions

Blanch haricots verts for 3–4 minutes, shock in cold water, and dry thoroughly.
Dredge shallots in flour and Smoky Cowboy. Fry in batches at 350°F for 2–3 minutes, until golden. Drain.
Heat oven to 375°F. Brown mushrooms in butter until dry, 12-15 minutes. Add onion and cook 4 minutes; add garlic and cook 1 minute.
Add flour and cook 2 minutes. Whisk in stock, milk, and cream; simmer 4–5 minutes until sauce coats a spoon. Finish with Mamma Limone! and Parmesan. Adjust seasoning as needed.
Fold in beans and transfer to a buttered 9 × 13-inch baking dish. Top with half the shallots.
Bake 20–25 minutes until bubbling. Add remaining shallots just before serving.

Notes

Make Ahead (Chef Brian Duffy): Prepare beans and sauce up to 2 days ahead. Combine and bake on serving day, allowing approximately 10 additional minutes if baking from cold. Store fried shallots airtight for up to 2 days.

For best texture, dry the blanched beans thoroughly before mixing with the sauce. Keep the remaining crispy shallots separate until serving.
