Nutritional yeast is lower in calories and adds a cheesy flavor.

Prepare a large pot of boiling water and season it generously.

Trim the green beans by removing the hard root end.

Add the green beans to the boiling water and blanch for about 1-2 minutes until bright green.

Plunge the blanched green beans into a bowl of ice water to stop the cooking process.

Use a fine mesh strainer to drain the green beans once they are cool.

In a saucepan over medium heat, melt some butter and add sliced onions, cooking until they are wilted and translucent (about 5 minutes).

Add sliced mushrooms to the onions and increase the heat to medium-high, cooking until the mushrooms release their liquid and turn golden brown.

Add minced garlic to the mushroom and onion mixture, cooking for about 1 minute until fragrant, and season with salt and pepper.

Scrape the mushroom and onion mixture out of the saucepan and set aside.

In the same saucepan, melt more butter over medium heat and add flour, whisking to break up clumps and cooking for about 1 minute.

Slowly stream in chicken broth while whisking to avoid lumps, then add milk and cook until the mixture simmers and thickens.

Taste the sauce and adjust seasoning with salt and pepper, then add the mushroom and onion mixture back into the sauce along with lemon juice.

Lay the blanched green beans in the bottom of a casserole dish and pour the mushroom onion filling over the top, ensuring all beans are covered.

Season the top with salt and pepper, then sprinkle a layer of fried shallots over it.

Cover the casserole with foil and bake for half the cooking time, then remove the foil to allow the shallots to crisp up.

Bake until the casserole is bubbly and the shallots are crispy.
