Ingredients

For the Topping

• 2 medium yellow onions, (thinly sliced)
• 7 tablespoons unsalted butter, (divided)
• 1/2 cup panko bread crumbs

For the Casserole

• 2 pounds fresh green beans, (trimmed)
• 1 pound cremini mushrooms, (quartered)
• 2 garlic cloves, (roughly chopped)
• 1 cup chicken broth
• 1 cup oat milk
• 1.5 tablespoons fresh thyme
• 1 tablespoon garlic powder
• 1/4 cup grated parmesan cheese
• Salt and pepper, (to taste)
• Olive oil, (for cooking)

How to Make Healthy Green Bean Casserole

Step 1: Preheat the Oven

Preheat your oven to 375° F. Fill a large pot with salted water and bring it to a boil. Thinly slice the onions and quarter the mushrooms. In a separate bowl, combine chicken broth with oat milk; set aside.

Step 2: Prepare the Onions

Heat olive oil in a large pan over medium heat. Add the onions, stirring occasionally for 10-12 minutes until they turn golden brown. Transfer them to a mixing bowl and toss with 2 tablespoons of melted butter, 1/4 cup flour, and panko until fully coated. Spread the onions onto a sheet pan and bake for 5–10 minutes until crispy.

Step 3: Cook the Green Beans

In the same pot of boiling salted water, cook the green beans for 4–5 minutes until almost tender. Drain them promptly and transfer them into a bowl filled with ice water to stop further cooking.

Step 4: Sauté Mushrooms

Using the same pan as before, add 2 tablespoons of butter over medium heat. Once hot, add mushrooms and sauté for about 3–4 minutes until they release their juices. Next, add garlic, thyme, salt, and pepper. Continue cooking for another 5–8 minutes until softened.

Step 5: Make the Sauce

In the same pan, melt 3 tablespoons of butter. Quickly whisk in 1/4 cup flour until a paste forms. Reduce heat to medium-low and slowly pour in the broth mixed with oat milk while whisking continuously until smooth. Stir in thyme, garlic powder, salt, pepper, and simmer for about 5 minutes. Remove from heat and whisk in parmesan cheese.

Step 6: Assemble & Bake

Grease your baking dish with olive oil. Combine cooked green beans with sautéed mushrooms and gravy in the dish; gently mix well. Cover with foil and bake for 20–25 minutes. Afterward, remove foil, place crispy onions on top, then bake uncovered for an additional 5–10 minutes or broil briefly for extra crispiness.

Common Mistakes to Avoid

When making a Healthy Green Bean Casserole, it’s easy to overlook some key details. Here are common mistakes to watch out for.

• Skipping the Ice Bath – Not cooling the green beans in an ice bath can make them soggy. Make sure to stop the cooking process immediately after boiling for the best texture.
• Overcooking the Onions – Cooking onions too long can lead to burnt bits and bitterness. Aim for a golden brown color, and keep stirring to avoid uneven cooking.
• Using Too Much Flour – Adding excessive flour can thicken the sauce too much. Start with less and gradually add more if needed until you reach your desired consistency.
• Neglecting Seasoning – Under-seasoned dishes fall flat in flavor. Taste your mushroom sauce and adjust salt and pepper before mixing everything together.
• Not Layering Properly – Distributing ingredients unevenly can affect cooking. Layer the green beans, mushrooms, and sauce well for even flavor throughout.
• Ignoring Baking Time – Failing to bake long enough can result in a casserole that feels incomplete. Follow timing closely to ensure proper heating and crispiness.
