This creamy spinach artichoke casserole with mushrooms, roasted garlic, and cheese is topped with French-fried onions for a flavor everyone will love.

Ingredients

6 cloves garlic, unpeeled
4 (10 ounce) packages frozen chopped spinach - thawed, drained and squeezed dry
1 (14 ounce) can artichoke hearts, drained and chopped
1/4 cup butter
1 (8 ounce) package sliced fresh mushrooms
3 green onions, finely chopped
1 (8 ounce) package cream cheese
1 cup sour cream
1 (8 ounce) can water chestnuts, drained and chopped
3/4 cup grated Parmesan cheese
3/4 cup real mayonnaise
2 teaspoons garlic salt
1 tablespoon lemon juice
1 cup French fried onion rings

Directions

1 Gather all ingredients. Preheat the oven to 350 degrees F (175 degrees C).
2 Place garlic cloves in a small oven-safe dish, and roast in the preheated oven until softened and fragrant, about 20 minutes. Set roasted garlic cloves aside to cool.
3 Place spinach in a large mixing bowl; stir in the artichoke hearts.
4 Melt butter in a skillet over medium heat. Add mushrooms; cook and stir until mushrooms are softened, about 10 minutes. Mix in green onions, and cook and stir until onions are soft, about 5 more minutes.
5 Transfer mushroom mixture into the bowl with spinach mixture.
6 Remove cream cheese from wrapping, place into a microwave-safe bowl, and cook in the microwave until warm and very soft, about 1 ½ minutes. Stir softened cream cheese into spinach mixture, and add sour cream, water chestnuts, Parmesan cheese, mayonnaise, garlic salt, and lemon juice.
7 Squeeze roasted garlic out of garlic skins, and mix thoroughly into the spinach mixture. Spoon the casserole into a round 2-quart baking dish.
8 Bake in the preheated oven until the casserole is hot and bubbly, about 30 minutes.
9 Spread French-fried onion rings over the top, return to the oven, and bake until the onion rings are lightly browned, 5 to 10 more minutes.
