Ingredients

For the creamy filling

• 2 cups pearl onions, peeled
• 3 cups fresh or frozen peas
• 2 tablespoons butter
• 2 tablespoons all-purpose flour
• 2 cups heavy cream
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• 1 cup grated Gruyère cheese (or cheese of your choice)
• Salt and pepper to taste

For the topping

• 1 cup panko breadcrumbs
• 1/4 cup grated Parmesan cheese
• 2 tablespoons melted butter
• Fresh parsley, chopped for garnish

Instructions

1. Preheat the oven: Preheat your oven to 375°F (190°C).

2. Cook the pearl onions: In a pot of boiling water, cook the pearl onions for about 5 minutes until slightly tender. Drain and set aside.

3. Make the creamy sauce: In a saucepan over medium heat, melt the butter. Stir in the flour to make a roux, cooking for about 2 minutes until lightly golden. Gradually whisk in the heavy cream, followed by garlic powder, onion powder, and salt and pepper to taste. Bring to a gentle simmer and cook until thickened, about 5-7 minutes. Stir in the Gruyère cheese until melted and smooth.

4. Combine the vegetables: In a large bowl, mix the cooked pearl onions and peas. Pour the creamy cheese sauce over the vegetables and stir until well combined.

5. Transfer to a baking dish: Pour the mixture into a greased 9x13 inch baking dish, spreading it evenly.

6. Prepare the topping: In a small bowl, combine the panko breadcrumbs, grated Parmesan cheese, and melted butter. Toss until the breadcrumbs are evenly coated.

7. Assemble and bake: Sprinkle the breadcrumb mixture over the vegetable and sauce mixture evenly. Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and crispy.

8. Garnish and serve: Remove from the oven, let it sit for a few minutes, then garnish with fresh parsley. Serve warm and enjoy!

🥄 Don't rush the creamy sauce! Taking the time to cook it slowly ensures it thickens perfectly without clumping, giving you that smooth texture in every bite.

Variations

• Vegetarian Delight: Substitute half of the heavy cream with vegetable broth for a lighter, yet still creamy, version.
• Add Spice: For a kick, sprinkle some red pepper flakes or chopped jalapeños into the cheese sauce before combining with the vegetables.
• Cheesy Goodness: Mix in an additional cup of your favorite cheese (like cheddar or mozzarella) for a cheesier au gratin.
• Savory Herbs: Experiment by adding fresh herbs like thyme or dill to the filling for an herbal twist.
