Spinach, Mushroom, and Artichoke Casserole: A Comforting Classic

My grandmother, bless her heart, was the queen of casseroles. Every family gathering, without fail, there would be a bubbling dish filled with some combination of vegetables, cheese, and a creamy sauce. While some were…questionable (green bean casserole, I’m looking at you), her spinach and artichoke casserole was always a hit. It was the first dish I ever tried to recreate myself, and to this day, the smell of it baking instantly transports me back to her cozy kitchen, surrounded by family and love. This recipe, inspired by that comforting memory, brings a touch of elegance to a familiar favorite.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 45-50 minutes
• Total Time: 1 hour 10 minutes
• Servings: 10-12
• Dietary Type: Vegetarian

Ingredients

• 2 tablespoons butter
• 1 cup chopped onion
• 2 cloves minced garlic
• Salt
• Pepper
• 1 lb sliced mushrooms
• 20 ounces frozen spinach, thawed and squeezed dry
• 1 can artichoke, drained and quartered
• 1 lb ricotta cheese
• 1 cup grated Monterey Jack cheese
• 1/2 cup crumbled feta
• 6 eggs
• Nutmeg
• 1/4 cup breadcrumbs
• 1/2 cup Parmesan cheese

Equipment Needed

• 13x9x2 inch baking pan
• Large skillet
• Large mixing bowl
• Small mixing bowl
• Whisk

Instructions

1. Begin by preheating your oven to 350°F (175°C). While the oven heats, grease a 13x9x2 inch baking pan. This will prevent the casserole from sticking and make serving easier.

2. In a large skillet, melt the 2 tablespoons of butter over medium heat. Add the 1 cup of chopped onion and 2 cloves of minced garlic. Sauté the onion and garlic until they are softened and fragrant, about 5-7 minutes. Season with salt and pepper to taste.

3. Add the 1 lb of sliced mushrooms to the skillet. Cook the mushrooms until they are soft and have released their moisture, about 8-10 minutes. Be sure to stir occasionally to ensure even cooking.

4. Remove the skillet from the heat and transfer the cooked onion, garlic, and mushroom mixture to a large bowl. Add the 20 ounces of thawed and squeezed dry spinach and 1 can of drained and quartered artichokes to the bowl.

5. Next, add the cheeses: 1 lb of ricotta cheese, 1 cup of grated Monterey Jack cheese, and 1/2 cup of crumbled feta to the bowl. Gently mix all of the ingredients together until they are well combined.

6. In a separate small bowl, whisk together the 6 eggs with a pinch of nutmeg. The nutmeg adds a subtle warmth and depth of flavor to the casserole.

7. Pour the egg mixture into the large bowl with the vegetable and cheese mixture. Gently fold everything together until the eggs are evenly distributed. Be careful not to overmix.

8. Pour the mixture into the prepared casserole dish. Sprinkle the top of the casserole evenly with 1/4 cup of breadcrumbs, followed by 1/2 cup of Parmesan cheese. The breadcrumbs will add a nice textural contrast, and the Parmesan cheese will create a golden-brown crust.

9. Bake in the preheated oven for 45-50 minutes, or until the casserole is set and the top is golden brown. To check for doneness, insert a knife into the center of the casserole. If the knife comes out clean, it is ready.

10. Let the casserole cool for a few minutes before serving. This will allow the filling to set up slightly and make it easier to slice and serve.

Expert Tips & Tricks

• Squeeze the spinach really dry: This is crucial to prevent a watery casserole. Use your hands or a clean kitchen towel to remove as much moisture as possible from the thawed spinach.
• Add some heat: For a spicy kick, add a pinch of red pepper flakes to the onion and garlic while sautéing.
• Make it ahead: The casserole can be assembled ahead of time and stored in the refrigerator for up to 24 hours. Add the breadcrumb and Parmesan topping just before baking. This makes it perfect for potlucks or holiday gatherings.
• Cheese variations: Feel free to experiment with different cheeses. Gruyere, provolone, or even a sharp cheddar would all be delicious additions.

Serving & Storage Suggestions

Serve the spinach, mushroom, and artichoke casserole warm as a main course or a side dish. It pairs perfectly with a simple green salad or some crusty bread.

To store leftovers, let the casserole cool completely before covering it tightly with plastic wrap or transferring it to an airtight container. Store in the refrigerator for up to 3-4 days.

To reheat, you can microwave individual portions or reheat the entire casserole in a preheated oven at 350°F (175°C) until heated through.

Do not leave the casserole at room temperature for more than 2 hours. Freezing is not recommended, as the texture of the ricotta cheese can change.
