• 8 oz cremini mushrooms, sliced
• 2 cloves garlic, minced
• 1/2 tsp dried thyme
• 3 tbsp whole wheat flour
• 1.5 cups low-sodium vegetable broth
• 1/2 cup 2% milk
• 1/2 tsp kosher salt

• 1/2 cup panko breadcrumbs

Step-by-Step

1. Preheat oven to 375F (190C) and lightly grease a 9×13 inch baking dish.

3. Heat olive oil in a large skillet over medium heat; sauté mushrooms until browned, approximately 8 minutes.
4. Stir in garlic and thyme, cooking for 1 minute until fragrant.
5. Sprinkle flour over mushrooms and cook for 1-2 minutes to remove raw flour taste.
6. Gradually whisk in vegetable broth and milk; simmer until the sauce thickens, about 5-7 minutes.
7. Season sauce with salt and pepper, then stir in the blanched green beans.
8. Transfer the mixture to the prepared baking dish.
9. In a small bowl, combine panko breadcrumbs, Parmesan, and crispy onions; sprinkle evenly over the casserole.
10. Bake for 20-25 minutes until the sauce is bubbly and the topping is golden brown.

Best Ways to Enjoy It

Serve this casserole warm and bubbly right out of the oven. It pairs beautifully with roasted turkey or herb-crusted chicken.

For a complete holiday spread, serve it alongside mashed potatoes. The creamy mushroom sauce acts like a delicious light gravy for your whole plate.

This dish is also great for a cozy Sunday dinner. It brings that comfort food feeling to any night of the week.

Keep It Fresh

Store any leftovers in an airtight container in the fridge. They will stay fresh for up to three to four days.

To reheat, place a portion in the oven at 350F. This helps the topping stay nice and crispy. Avoid the microwave if you want to keep that crunch.

You can also prep the components a day early. Just wait to add the topping until you are ready to bake. This is a huge time-saver for busy holiday mornings.

Tips for Best Results

• Use fresh green beans for the best possible texture.
• Do not skip the ice bath after blanching the beans.
• Sauté the mushrooms until they are deeply browned for flavor.
• Whisk the sauce constantly to avoid any flour lumps.
• Grate your own Parmesan cheese for a better melt.
• Watch the panko topping closely so it does not burn.
• Use a large skillet to make the sauce easily.
• Lightly grease your baking dish for very easy cleanup.

Ways to Switch It Up

• Add cooked bacon bits for a delicious smoky flavor.
• Use gluten-free flour and breadcrumbs to make it GF.
• Stir in a pinch of red pepper flakes for heat.
• Swap cremini mushrooms for wild mushrooms for earthy depth.
• Add a splash of dry white wine to the sauce.

Common Questions

Can I use frozen green beans?

Yes, you can use frozen beans if needed. Just make sure to thaw and drain them very well. Fresh beans will always provide the best crunch and flavor.

Can I make this recipe vegan?

You can easily swap the milk for unsweetened almond milk. Use nutritional yeast instead of Parmesan for that cheesy taste. It will still be creamy and delicious.

How do I prevent a watery casserole?

The key is to drain your blanched beans completely. Pat them dry with a towel if you need to. Also, let the mushroom sauce thicken fully before adding the beans.

This is the only green bean casserole you will ever need. Enjoy every bite!
