Step-by-Step Instructions
Step 1 — Prep the Green Beans
Trim the ends from 1½ pounds of fresh green beans and cut them into 1- to 2-inch pieces. If using frozen green beans, thaw them completely and pat dry to remove excess moisture.
Blanch fresh beans in boiling salted water for 4–5 minutes until bright green and tender-crisp, then immediately transfer to an ice bath to stop the cooking process.
Step 2 — Make the Creamy Sauce
In a large skillet, melt 3 tablespoons of butter over medium heat. Whisk in 3 tablespoons of all-purpose flour and cook for 1 minute until golden and fragrant.
Gradually whisk in 1½ cups of whole milk and 1 cup of chicken or vegetable broth until smooth. Simmer, stirring constantly, until the sauce thickens enough to coat the back of a spoon.
Step 3 — Season the Sauce
Stir in ½ cup of sour cream, 1 teaspoon of garlic powder, 1 teaspoon of onion powder, and ½ teaspoon of black pepper. Taste and adjust seasoning with salt as needed.
For extra flavor, add a dash of Worcestershire sauce or a pinch of cayenne pepper. The sauce should be well-seasoned since it will be diluted slightly by the green beans.
Step 4 — Combine Beans and Sauce
Add the prepared green beans and 1 cup of fried onions to the sauce, folding gently to coat everything evenly without breaking the beans.
If the mixture seems too thick, add a tablespoon or two of additional broth. The consistency should be creamy but not soupy.
Step 5 — Transfer to Baking Dish
Pour the green bean mixture into a greased 9×13-inch baking dish and spread it into an even layer. For easier cleanup, you can line the dish with parchment paper.
At this stage, the Green Bean Casserole Recipe can be covered and refrigerated for up to 24 hours before baking if preparing ahead.
Step 6 — Add the Topping
Sprinkle 1½ cups of fried onions evenly over the top of the casserole. For extra crunch, mix the onions with ¼ cup of panko breadcrumbs and 2 tablespoons of melted butter.
Reserve about ¼ cup of onions to add during the last 5 minutes of baking for maximum crispiness.
Step 7 — Bake the Casserole
Bake uncovered at 375°F (190°C) for 25–30 minutes until the sauce is bubbly around the edges and the topping is golden brown.
The casserole is done when an instant-read thermometer inserted into the center reads 165°F (74°C). If the topping browns too quickly, tent with foil.
Step 8 — Rest and Serve
Let the Green Bean Casserole Recipe rest for 5–10 minutes before serving. This allows the sauce to thicken slightly and makes serving easier.
Garnish with fresh parsley or thyme if desired. Serve warm as a perfect side dish for holiday meals or weeknight dinners.

Common Mistakes to Avoid
- Mistake: Using canned green beans, which become mushy. Fix: Opt for fresh or frozen green beans to maintain a crisp-tender texture and better flavor.
- Mistake: Overcooking the casserole, causing a watery sauce. Fix: Bake just until bubbly and golden to preserve the creamy consistency of your Green Bean Casserole Recipe.
- Mistake: Skipping the step of sautéing aromatics like onions or garlic. Fix: Sauté them first to build a deeper, more complex flavor base for the sauce.
- Mistake: Using a thin, runny cream soup as the base. Fix: Choose a condensed, cream-style soup or make a thick roux-based sauce from scratch.
- Mistake: Not seasoning the sauce adequately before baking. Fix: Taste and adjust salt, pepper, and a pinch of nutmeg or soy sauce for umami depth.
- Mistake: Adding soggy or store-bought fried onions only at the end. Fix: Stir half into the casserole for flavor, then top with the rest for maximum crunch.
- Mistake: Using a shallow baking dish that spreads the mixture thin. Fix: Use a deeper dish to keep the casserole moist and prevent the topping from burning.
- Mistake: Not blanching fresh green beans before assembling. Fix: Briefly boil and shock them in ice water to set their vibrant color and ideal texture.
- Mistake: Overmixing the ingredients, which can break the beans. Fix: Gently fold everything together just until combined to keep the structure intact.
Storing Tips
- Fridge: Cool your Green Bean Casserole Recipe completely before transferring to an airtight container. Refrigerate for up to 3-4 days.
- Freezer: Freeze this casserole in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Reheat: Reheat portions in a 350°F oven until the internal temperature reaches 165°F, about 20-30 minutes. Add a splash of broth if it seems dry.
Always ensure your Green Bean Casserole Recipe reaches a safe internal temperature of 165°F when reheating to prevent foodborne illness.
