How to make Vegetable Casserole

Preheat oven to 390°F and set a 8×11 inch casserole aside.

For the green beans:

They should be cooked or steamed when starting to make this vegetable bake because it will save you time. If you are using canned green beans, you can totally skip this step of curse. Add them to a bowl and mix with the corn.

Cheesy white sauce is given over the vegetables in a large mixing bowl.

Making the cheesy sauce:

Heat 4 Tbsp vegan butter (reserve remaining 2 Tbsp for the topping).

Add onions and garlic and fry for 1 minute. Add flour and almond milk, and stir until the sauce thickens. Turn from medium to low heat and slowly add vegan sour cream, vegan parmesan (reserve 2 Tbsp for the topping) and cheddar, and nutmeg.

Season with a pinch of salt and pepper and let simmer for 2 minutes on low heat. Stir occasionally. Add to the green beans with the corn set a side.

Vegetables mixed with sauce are transferred to a casserole dish.

For the crunchy topping of the Vegetable Casserole

In a food processor, combine remaining vegan butter with parmesan and crackers. Pulse until you have crumbled texture, then add almonds. Pulse one more time.

Finally for the making the Vegetable Casserole

Transfer green beans with corn and sauce into your casserole dish, add the prepared topping on top. Bake for 15 minutes, then allow to cool for 2 minutes before serving on plates.

Crunchy topping ingredients are given into the bowl of a food processor and after pulsing given over the casserole.

Storage tips

You can keep leftovers in the fridge for around 4 days. It is a great meal that you can make ahead.

You can also absolutely freeze the Vegetable Casserole, but keep in mind: to always let it cool down completely before it goes into the freezer. It will last for around 3 months.

I recommend you freeze it without the topping and prepare that one fresh. Same goes for reheating, thaw completely overnight
