Green Bean Casserole Recipe Rumble
the classic holiday casserole and “rumbles it up” — bigger flavor, richer sauce, deeper seasoning, and a layered baking approach that keeps the beans vibrant and the topping ultra-crisp. Perfect for Thanksgiving, Christmas, potlucks, or anytime you want bold, comforting, crowd-pleasing food.
INGREDIENTS
For the Green Beans
-
2 lbs fresh green beans, trimmed and cut into 1½–2 inch pieces
-
1 Tbsp salt for blanching water
-
Ice bath (large bowl of ice + cold water)
For the Creamy Mushroom Sauce
-
4 Tbsp butter
-
1 Tbsp olive oil
-
12 oz fresh mushrooms, sliced (mix of cremini + button for best flavor)
-
1 medium onion, finely diced
-
4 cloves garlic, minced
-
1 ½ tsp kosher salt
-
½ tsp black pepper
-
½ tsp smoked paprika (Rumble twist)
-
¼ tsp white pepper (optional but great)
-
1/4 cup all-purpose flour
-
2 cups chicken broth (or vegetable broth)
-
1 ½ cups heavy cream
OR 1 cup half-and-half + ½ cup whole milk for a lighter version -
1 Tbsp Worcestershire sauce
-
½ tsp dried thyme or 1 tsp fresh thyme leaves
-
1/3 cup grated Parmesan (adds savory depth)
-
Splash of sherry or white wine (optional but highly recommended)
For the Topping
-
2 cups French-fried onions
-
1 cup panko breadcrumbs
-
2 Tbsp melted butter
-
½ tsp paprika
-
Pinch of salt and black pepper
INSTRUCTIONS
1. Blanch the Green Beans (Keeps them crisp and colorful)
-
Bring a large pot of salted water to a rolling boil.
-
Add green beans and cook 4–5 minutes until bright green and just tender.
-
Immediately drain and plunge into an ice bath to stop cooking.
-
Drain again and pat dry. Set aside.
Rumble Tip:
Drying the beans keeps the sauce from thinning out.
2. Make the Mushroom Cream Sauce
-
Heat butter and olive oil in a deep skillet over medium-high heat.
-
Add mushrooms and cook 8–10 minutes, letting them brown deeply before stirring.
-
Add onions and cook another 5 minutes until soft.
-
Stir in garlic; cook 1 minute until fragrant.
-
Season with salt, black pepper, smoked paprika, and thyme.
-
Sprinkle flour over mixture and stir to coat — cook 2 minutes to remove raw flour flavor.
-
Slowly pour in chicken broth, whisking until smooth.
-
Add heavy cream, Worcestershire sauce, Parmesan, and optional splash of sherry.
-
Simmer 5–7 minutes until thickened and silky.
Rumble Note:
The sauce should be thick enough to coat a spoon heavily — richer than the canned-soup classic.
3. Combine Beans & Sauce
-
Add the blanched green beans into the mushroom sauce.
-
Fold gently to avoid breaking the beans.
-
Taste and adjust seasoning — you may want an extra pinch of salt or pepper.
4. Make the Crispy Topping
In a bowl, combine:
-
French-fried onions
-
Panko breadcrumbs
-
Melted butter
-
Paprika
-
Salt and pepper
Toss until everything is evenly coated.
The panko makes it extra crunchy; the onions give classic flavor.
5. Assemble & Bake
-
Preheat oven to 375°F (190°C).
-
Transfer mixture into a greased 9×13 casserole dish.
-
Bake 15 minutes, uncovered.
-
Remove and sprinkle topping evenly over the surface.
-
Return to oven and bake another 15–20 minutes, until topping is golden brown and centers are bubbling.
SERVING NOTES (Rumble Style)
-
Let casserole rest 10 minutes before serving so sauce thickens.
-
Add a dash of smoked paprika or hot sauce on top right before serving for a flavor punch.
-
Works great alongside turkey, ham, roast beef, or pork loin.
MAKE-AHEAD OPTION
-
Prepare beans and sauce, combine, and place in casserole dish.
-
Cover tightly and refrigerate up to 24 hours.
-
Add topping only right before baking.
-
Bake 10 minutes longer if baking cold from the fridge.
