Ingredients

• 3 large Parsnips
• 1 medium head Cauliflower
• 1 large Yellow Onion
• 3 cloves Garlic
• 3 tablespoons Olive Oil
• 2 tablespoons Unsalted Butter
• 0.333 cup Heavy Cream
• 1 teaspoon Salt
• 0.5 teaspoon Black Pepper
• 2 teaspoons Fresh Thyme Leaves
• 0.25 cup grated Parmesan Cheese
• 0.25 cup Breadcrumbs

Directions

Step 1

Preheat your oven to 375°F (190°C).

Step 2

Peel and chop the parsnips into 1-inch chunks. Break the cauliflower into florets and roughly chop the onion.

Step 3

Bring a large pot of salted water to a boil. Add the parsnips and cauliflower, and cook for 15-20 minutes until fork-tender.

Step 4

While the vegetables cook, heat 1 tablespoon of olive oil in a skillet over medium heat. Add the chopped onion and sauté until softened and golden, about 8-10 minutes. Add minced garlic (2 minutes before the onions finish sautéing) and cook until fragrant.

Step 5

Drain the cooked parsnips and cauliflower, and transfer them to a large mixing bowl. Add the sautéed onions and garlic, 2 tablespoons of butter, heavy cream, salt, black pepper, and thyme leaves. Using an immersion blender or potato masher, blend or mash until smooth and creamy.

Step 6

Lightly grease a medium-sized baking dish with 1 tablespoon of olive oil. Spread the mashed mixture evenly into the dish.

Step 7

In a small bowl, mix the breadcrumbs, Parmesan cheese, and 1 tablespoon of olive oil. Sprinkle the mixture evenly over the top of the mashed vegetables.

Step 8

Bake in the preheated oven for 15-20 minutes, or until the top is golden and crispy.

Step 9

Remove from the oven, let cool slightly, and serve warm. Enjoy!
