Simple Ingredients

• 1.5 lbs fresh green beans, trimmed and halved
• 1 tbsp olive oil
• 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
• 1/4 tsp black pepper
• 1/2 cup panko breadcrumbs
• 1/4 cup grated Parmesan cheese
• 1/4 cup crispy fried onions

Step-by-Step Directions

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

This dish looks beautiful when served in a bright white ceramic dish. The green beans pop against the golden, cheesy breadcrumb topping. It is the perfect companion for a roasted turkey or chicken.

Pair it with a crisp autumn salad for a balanced meal. It also works well alongside mashed cauliflower for a lighter holiday. This is truly the ultimate Holiday/Entertaining side dish for any crowd.

Keep It Fresh

You can store any leftovers in an airtight container for three days. Keep them in the refrigerator to maintain the best texture. Reheat individual portions in the oven at 350F to keep the topping crisp.

Microwaving works too, but the breadcrumbs may soften slightly. You can even assemble the filling a day in advance. Just add the topping right before you slide it into the oven.

Tips for Best Results

• Don’t skip the ice bath after blanching your green beans.
• Avoid using canned beans to keep the texture crisp and fresh.
• Substitute gluten-free flour if you have dietary restrictions in the family.
• Use pre-sliced mushrooms to save extra time during holiday meal prep.
• Incorporate a pinch of nutmeg to elevate the savory mushroom sauce.
• Ensure the sauce is thick before adding the beans to the skillet.
• Spread the topping right to the edges for maximum crunch.

Make It Your Own

• Add toasted almonds for a nutty Fall twist on the topping.
• Swap the milk for unsweetened almond milk to make it dairy-free.
• Stir in some red pepper flakes for a subtle spicy kick.
• Use frozen green beans if fresh ones are not available at market.

Common Questions

Can I make this ahead of time?

Yes, you can prepare the bean and sauce mixture early. Store it in the fridge and add the topping before baking. This is great for holiday planning.

Are fresh beans better than canned?

Fresh beans provide a much better snap and flavor profile. They hold up well in the creamy sauce without becoming mushy. Your Healthy Green Bean Casserole will taste much more vibrant.

How do I know when it is done?

Look for the sauce to be bubbling around the edges. The panko topping should be a beautiful golden brown color. This usually takes about 20 to 25 minutes.

I hope this fresh side dish brings extra joy to your holiday table. It is proof that eating well can still be incredibly delicious. Happy cooking!
