Ingredients
Scale
Vegetables:
- 1 pound fresh green beans, trimmed
- 8 ounces sliced cremini mushrooms
- 1 medium yellow onion, chopped
Main Sauce Components:
- 2 cups milk (whole or 2%)
- ½ cup vegetable broth
- ¼ cup all-purpose flour
- 1 tablespoon olive oil
Seasonings and Toppings:
- 6 ounces crispy fried onions
- ½ teaspoon salt, plus more to taste
- ¼ teaspoon black pepper, plus more to taste
- 1 teaspoon soy sauce
- ¼ teaspoon garlic powder
- ¼ teaspoon onion powder
Instructions
- Rinse and trim 1 pound of fresh green beans. Slice 8 ounces of cremini mushrooms into thin pieces.
- Heat 1 tablespoon olive oil in a large skillet over medium heat. Sauté 1 chopped yellow onion until translucent and soft, approximately 6 minutes.
- Add prepared green beans and mushrooms to the skillet. Sprinkle ½ teaspoon salt and ¼ teaspoon black pepper. Cook while stirring occasionally until vegetables are tender-crisp, around 9 minutes.
- Remove vegetable mixture from skillet and set aside. Lower heat to medium-low.
- Dust ¼ cup flour into the empty skillet. Stir constantly for 2 minutes to prevent burning.
- Gradually whisk 2 cups milk and ½ cup vegetable broth into the flour, creating a smooth sauce.
- Simmer sauce for 6 minutes, stirring continuously until it thickens. Mix in 1 teaspoon soy sauce, ¼ teaspoon garlic powder, and ¼ teaspoon onion powder.
- Preheat your oven to 350°F. Return vegetable mixture to the sauce and combine thoroughly.
- Transfer mixture to a 9×13 inch baking dish. Spread evenly across the surface.
- Sprinkle 3 ounces crispy fried onions over the casserole.
- Bake for 22 minutes until edges become bubbly and golden.
- Top with remaining 3 ounces crispy fried onions. Bake an additional 5 minutes.
- Allow casserole to rest 4 minutes before serving to help sauce set.
Notes
- Fresh green beans make a huge difference, so choose crisp, bright green beans without blemishes or soft spots.
- Slice mushrooms thin and evenly to ensure they cook consistently and blend smoothly with the creamy sauce.
- For a gluten-free version, replace wheat flour with cornstarch or a gluten-free flour blend and use tamari instead of soy sauce.
- If you prefer a lighter dish, swap heavy cream for half-and-half or whole milk, which will reduce the total calories while maintaining a creamy texture.
