Ingredients
Detailed Instructions for Broccoli and Cheddar Quinoa Gratin
Preheat the oven to 400°F (200°C). Lightly grease an 8x8-inch baking dish (or a similarly sized casserole dish) with vegetable oil or nonstick cooking spray. Set aside.
In a medium-sized saucepan, heat 1 tablespoon of olive oil over medium heat. Once the oil is shimmering, add the diced onion and minced garlic. Season with sea salt and freshly ground black pepper to taste. Sauté for 4–5 minutes, stirring occasionally, until the onions are translucent and fragrant.
Stir in the rinsed and drained quinoa along with 1 teaspoon of dried dill. Cook for an additional 2–3 minutes, stirring frequently, to lightly toast the quinoa and deepen its flavor.
Pour in the 2 cups of vegetable broth, and bring the mixture to a gentle boil. Once boiling, reduce the heat to low, cover the pot with a lid, and let it simmer for 12 minutes.
After 12 minutes, remove the pot from heat but keep it covered. Let it sit undisturbed for 5 more minutes to allow the quinoa to finish steaming.
Uncover the pot and stir in the broccoli florets. Add the heavy cream and shredded white cheddar cheese. Stir continuously until the cheese has completely melted and the mixture is thick, creamy, and well combined. Taste and adjust seasoning with additional salt and pepper, if needed.
Carefully transfer the quinoa and broccoli mixture into the prepared baking dish, spreading it evenly with a spatula.
In a small mixing bowl, combine the breadcrumbs, melted butter, and grated parmesan cheese. Mix well until the breadcrumbs are evenly coated.
Sprinkle the breadcrumb mixture evenly over the top of the gratin.
Transfer the dish to the preheated oven and bake for 10 to 15 minutes, or until the topping is golden brown and bubbling around the edges.
Remove from the oven and allow the gratin to rest for 5 minutes before serving. Garnish with freshly chopped parsley, and enjoy!
