- 3/4 cup vegetable broth: Homemade or store-bought, it’s the base of the sauce.

Step-by-Step Instructions

Follow these simple steps to create your Vegan Green Bean Casserole:
- Preheat your oven to 400 degrees F (204 C). Bring a large pot of water to a boil and salt it well. Add the green beans and cook for 5 minutes. Drain and place them in an ice water bath to stop the cooking process. Drain again and set aside.
- Prepare the sauce: In a large oven-safe skillet over medium heat, add the vegan butter or olive oil, shallots, and garlic. Season with salt and pepper, stirring for 2-3 minutes until fragrant. Add the mushrooms and cook for an additional 3-4 minutes until lightly browned.
- Create the roux: Sprinkle in the flour, whisking to coat the veggies. Cook for 1 minute, then gradually add the vegetable broth while whisking to combine.
- Incorporate the almond milk: Add the almond milk, continuing to whisk. Season again with salt and pepper, then bring the mixture to a simmer. Reduce the heat and let it thicken for 5-7 minutes, stirring occasionally.
- Combine ingredients: Once the sauce is thick and bubbly, remove it from heat. Gently fold in 1/3 of the fried onions and all the cooked green beans, ensuring they are well coated.
- Bake the casserole: Top with the remaining fried onions and bake in the preheated oven for 15 minutes, or until warmed through and slightly browned on top. Serve immediately.
- Store leftovers: This casserole keeps well in the fridge for up to a few days, making it perfect for meal prep!
Pro Tips for the Perfect Casserole
- Blanching the green beans: This step helps retain their vibrant color and crunch. Don’t skip it!
- Adjusting seasonings: Taste the sauce before mixing with the green beans and adjust seasonings to your preference.
- Adding spices: Incorporate spices like thyme or nutmeg for an extra flavor boost!
- Using fresh herbs: Garnish with fresh parsley or thyme before serving for a pop of color and freshness.
- Experiment with toppings: Try adding crushed nuts or breadcrumbs for a different texture.
- Making it gluten-free: Substitute all-purpose flour with cornstarch or a gluten-free flour blend.
- Vegan cheese option: If you enjoy cheesy flavors, sprinkle some vegan cheese on top before baking.
- Serve with a side salad: Balance the richness of the casserole with a light salad for a complete meal.
Common Mistakes & Troubleshooting
Even the best cooks can run into a few hiccups. Here’s how to avoid common mistakes:
- Overcooking the green beans: Be sure to blanch just until tender-crisp to maintain texture.
- Not enough seasoning: Always taste your sauce and adjust seasoning before combining everything.
- Using stale fried onions: Fresh crispy onions will keep the casserole crispy; check the expiration date!
- Skipping the ice bath: This crucial step stops cooking and keeps green beans vibrant.
Delicious Variations
Feel free to customize your casserole! Here are some tasty variations:
- Mushroom medley: Use a mix of different mushrooms for a more complex flavor profile.
- Cheesy vegan version: Add nutritional yeast or vegan cheese to the sauce for a cheesy twist.
