The most delicious healthy bean casserole

I don't know about you, but I can always go for some tasty green bean casserole. I feel like a lot of people share my opinion, so why is it seemingly always limited to holidays and special occasions?! If it were up to me, green bean casserole would be present at least monthly. At least.

After you try this healthy green bean casserole recipe, I can guarantee you're going to feel the same way.

This recipe takes everything good about green bean casserole and up-levels it to a healthier place. We remove a couple of the less nutrient-rich ingredients and replace them with things that are just as flavorful, like cremini mushrooms and parmesan cheese.

Ingredients in this healthy green bean casserole recipe

When it comes to this casserole's ingredients, each item plays an important role. Some contribute to the flavor, others to the texture and density. When all is said and done, you're left with a delicious casserole that's perfect for gatherings or just for the family!

Green beans: Begin with 2 lbs of green beans. Since these are the main ingredient in the dish, we're loading them in!
Olive oil: Next, set aside 2 tablespoon of olive oil. This will be used to sauté the yellow onion.
Yellow onion: You will need 1 small yellow onion, finely diced.
Mushrooms: Include 10 oz of cremini mushrooms for flavor.
Garlic: Next, season things up with 5 cloves of minced garlic.
Salt & Pepper: Include 1 teaspoon each of salt and pepper.
Nutmeg: ¼ teaspoon of nutmeg adds some earthy spice (but not hot) flavor.
Parmesan cheese: 2 tablespoon of parmesan cheese will be used in the filling.
Broth: Next, use ½ cup of chicken broth to add density to the sauce.
Almond milk: 1 cup of unsweetened almond milk thickens up the casserole filling.
Arrowroot powder: 2 tablespoon of arrowroot powder is just enough powder to help the filling reach the correct consistency.
Broth: You will need an additional 3 tablespoon of broth.
Olive oil: 2 tablespoon of olive oil is used to cook the shallots.
Shallots: You will need about 5 shallots, and they should be sliced into rings.
Parmesan: Finally, the dish is complete with ¼ cup of parmesan cheese.

Tools needed to make healthy fresh green bean casserole

When it comes to kitchen tools, you'll need a few cooking pots, measuring cups, a mixing bowl, and a couple of other items. Here's a full list:

Pot
Strainer
Pan
Spatula or stirring utensil
Mixing bowl
Whisk
8x11 baking dish

For measuring, you'll need the following sized cups: ¼ tsp, 1 tsp, 1 tbsp, ¼ cup, ½ cup, and 1 cup.

How to make healthy green bean casserole

It will take about 15 minutes to prep the casserole. After that, let the oven do the work as it bakes for around 40 minutes.

Begin by preheating the oven to 350ºF.

Add the green beans to boiling water for 6-7 minutes, and then drain and rinse with cold water.

Heat the olive oil over medium-high heat. Add the onion and mushrooms and cook for about 5 minutes or until softened. Add the garlic, salt, pepper, and nutmeg, and stir in the parmesan cheese.

Finally, add the chicken broth and almond milk.

In a separate bowl, whisk together the arrowroot power and additional chicken broth. Pour the mix into the onion and mushroom mixture. This will help to thicken the sauce over the next several minutes.

Once thick, pour ¼ of the sauce mixture into the bottom of an 8x11 baking dish.

Add the green beans to the dish and then pour the rest of the sauce mixture on top.

Bake for 40 minutes.

While baking, heat the olive oil and cook the shallots over high heat for 4-5 minutes or until they turn golden brown. They will burn easily, so keep your eye on them. Drain on a paper towel.

Once the casserole is done, add the crispy shallots and parmesan cheese to the top.

What makes this casserole healthier?

Most green bean casseroles consist of about 4 ingredients - green beans, cream of mushroom soup, salt, and fried onion pieces. While those recipes are a breeze to make, they simply don't pack in all of the nutrients that this recipe provides! To make this healthier and add lots of flavor, we're making two big changes.

Broth, almond milk, and mushrooms
First, we're skipping cream of mushroom soup and instead using a blend of broth, almond milk, mushrooms, and spices to achieve the same flavor and result. A few other ingredients help with the consistency, like arrowroot powder and parmesan.

Parmesan cheese
Next, we're ditching the fried onions and using a parmesan cheese coating instead. This is my favorite way to make green bean casserole because the cheese becomes golden brown and makes a delicious top layer!
