Ingredients

• 3 tablespoons olive oil
• 1 large (finely diced) yellow onion
• 4 minced garlic cloves
• 450 grams (sliced) cremini mushrooms
• 1 teaspoon (chopped) fresh thyme
• 1 teaspoon ground paprika
• 2 tablespoons all-purpose flour
• 480 milliliters vegetable broth
• 2 400-gram cans (drained and rinsed) canned white beans
• 100 grams baby spinach
• 100 grams bread crumbs
• 50 grams (grated, optional for garnish) parmesan cheese
• 0 to taste salt
• 0 to taste black pepper

Directions

Step 1

Preheat your oven to 200°C (400°F).

Step 2

Heat 2 tablespoons of olive oil in a large skillet over medium heat.

Step 3

Sauté the diced onion for 3-4 minutes until soft and translucent.

Step 4

Add the minced garlic and cook for an additional minute, stirring frequently.

Step 5

Add the sliced mushrooms to the skillet and cook for 6-8 minutes, stirring occasionally, until they release their moisture and start to brown.

Step 6

Stir in the chopped thyme and paprika, cooking for another minute to release their aromas.

Step 7

Sprinkle the flour over the mushroom mixture and stir well to coat. Cook for 1 minute to remove the raw flour taste.

Step 8

Slowly pour in the vegetable broth, stirring constantly, to create a creamy sauce. Allow the mixture to simmer for 3-4 minutes until slightly thickened.

Step 9

Add the drained white beans and baby spinach to the skillet. Stir gently to combine and cook until the spinach wilts, about 2 minutes.

Step 10

Season the mixture with salt and pepper to taste and transfer everything to a greased 9x13-inch casserole dish.

Step 11

In a small bowl, mix the bread crumbs with the remaining 1 tablespoon of olive oil. Sprinkle this mixture evenly over the casserole.

Step 12

If using, sprinkle grated parmesan cheese on top.

Step 13

Bake the casserole in the preheated oven for 20-25 minutes or until the top is golden brown and crispy.

Step 14

Let the casserole cool for 5 minutes before serving. Enjoy!
