Step-by-Step Instructions
Active Time: 15 mins | Total Time: 1 hr | Servings: 8
Ingredients
- 2 cups water
- 1 cup quinoa (white, red, or black)
- 1 tablespoon extra-virgin olive oil
- ½ teaspoon salt, divided
- 4 cups small broccoli florets and chopped stems
- 1 (15.5 ounce) can no-salt-added cannellini beans, rinsed
- 1 cup whole milk
- 1 cup whole-milk plain Greek yogurt
- 2 tablespoons chopped fresh thyme, plus more for garnish
- 3 cloves garlic, finely chopped
- ¾ teaspoon ground pepper
- ½ teaspoon onion powder
- 2 cups shredded Fontina cheese, divided
Directions
Step 1: Preheat your oven to 350°F and position the rack 5 inches from the broiler. Lightly coat a 13x9-inch broiler-safe baking dish with cooking spray. In a large saucepan, combine water, quinoa, olive oil, and ¼ teaspoon salt. Bring to a boil over medium-high heat, then reduce to medium-low, cover, and cook undisturbed for 10 minutes. Add broccoli (do not stir), cover, and continue cooking until all the water is absorbed (about 5 minutes). Remove from heat and let stand, covered, for 5 minutes.
Step 2: Transfer the quinoa mixture to a large bowl. Add cannellini beans, milk, yogurt, thyme, garlic, pepper, onion powder, 1½ cups cheese, and the remaining ¼ teaspoon salt. Gently stir until evenly combined. Spoon the mixture into the prepared baking dish and sprinkle with the remaining ½ cup cheese.
Step 3: Bake until heated through and the cheese is melted (about 15 minutes). Switch the oven to broil (without removing the dish) and broil until the top is lightly browned (about 3 minutes). Let cool for 5 minutes, garnish with additional thyme, and serve!
Expert Tips from the RicetteGourmet Test Kitchen
- Frozen Broccoli Hack: Save time by using frozen broccoli. Thaw and dry it thoroughly to avoid excess moisture.
- Quinoa Varieties: White quinoa is recommended, but red or black quinoa works too. Adjust cooking times as needed.
- Reheating: Let a chilled casserole sit at room temperature for 30-60 minutes before reheating to prevent drying out.
- Cheese Substitutes: No Fontina? Try Gruyère, Gouda, or mild provolone for a similar flavor.
Make-Ahead & Storage Tips
- Prep Ahead: Chop broccoli up to 1 day in advance.
- Storage: Store cooked casserole in the fridge for up to 4 days or freeze for up to 3 months. Thaw overnight before reheating.
- Reheating: Warm in a 350°F oven or microwave until heated through.
