Plus, it doesn't use French Onion Soup mix. I think the mix tastes okay, but it always leaves a funky aftertaste that lasts for a full day. Yuck.

French
Onion and Mushroom Rice Casserole
Ingredients
- 5 ½ cups rice, cooked (mix of brown and white)
- 3 Tablespoons butter
- 1 jumbo sweet onion or 2 small sweet onions, chopped
- 1/2 cup beef broth
- 1 Tablespoon gluten-free Worcestershire sauce
- 3/4 teaspoon dried thyme
- 1/2 teaspoon sugar
- 1 bay leaf
- salt and pepper
- 8oz mushrooms, thinly sliced
- 3 cloves garlic, minced
- 5 teaspoons flour
- 2 cups milk, divided
- 6oz shredded fontina (or Monterey jack) cheese, divided
- 1/4 cup + 2 Tablespoons freshly grated parmesan cheese, divided
- 1/3 cup regular or light sour cream
Directions
- Spray a 9x9" baking dish (or equivalent-sized baking dish) with nonstick spray then set aside. Place a large skillet over high heat then add butter, onions, beef broth, worcestershire sauce, dried thyme, sugar, bay leaf, salt, and pepper. Bring liquid to a boil then turn heat down to just a touch above medium and simmer until onions begin to soften and broth is nearly absorbed, 10 minutes, stirring occasionally.
- Add mushrooms to skillet with onions then turn heat up to medium-high and saute until mushrooms are tender, 5-7 minutes. Add garlic, season with salt and pepper, then saute for 1 more minute. Remove bay leaf then scoop mixture onto a plate and set aside.
- Whisk together flour and 1/2 cup milk in a small dish then pour into skillet. Add remaining 1-1/2 cups milk, season with lots of salt and pepper, then let the mixture come to a bubble, stirring constantly. Turn heat down to medium then simmer until liquid is thickened and bubbly, 8-10 minutes, stirring constantly. Remove skillet from heat then stir in 4oz fontina cheese, 1/4 cup parmesan cheese, and sour cream. Taste then add salt and pepper if necessary.
- Add the cooked rice and mushroom/onion mixture to the cheese sauce then stir to combine and scoop into the prepared baking dish. Top with remaining shredded fontina and parmesan cheese, then broil until golden brown.
