Description
An elegant French-inspired brunch dish that transforms Brussels sprouts through caramelization into sweet, nutty perfection, then nestles them in a creamy Gruyere-topped egg custard.
Prep Time: 10 minutes | Cook Time: 25 minutes | Total Time: 35 minutes | Servings: 6-8
Ingredients
- 8 oz Brussels sprouts, trimmed and halved (about 2 cups, look for tight, green heads)
- 6 large eggs (room temperature for best mixing)
- 1/4 cup milk (whole milk creates the creamiest texture)
- 1/2 tsp salt (kosher salt preferred)
- 1/4 tsp black pepper (freshly ground is best)
- 1 tbsp olive oil (extra virgin for best flavor)
- 1/2 cup shredded Gruyere cheese (don’t substitute—this is what makes it special)
- 2 tbsp chopped fresh parsley (for color and freshness)
Instructions
- Preheat oven to 350°F (175°C). Make sure your skillet is oven-safe before starting.
- In a large oven-proof skillet, heat olive oil over medium heat. Add Brussels sprouts cut-side down and cook without moving until caramelized, about 8-10 minutes.
- In a bowl, whisk together eggs, milk, salt, and black pepper until well combined and slightly frothy.
- Pour egg mixture over the caramelized Brussels sprouts in the skillet—don’t stir, just let it settle naturally.
- Cook without stirring for 4-5 minutes until edges start to set but center remains jiggly.
- Sprinkle shredded Gruyere cheese evenly on top of the frittata.
- Transfer skillet to preheated oven and bake for 12-15 minutes until frittata is just set in the middle (slight jiggle is perfect).
- Remove from oven and let cool slightly—this helps it set completely.
- Sprinkle chopped fresh parsley over the frittata for color and brightness.
- Slice and serve warm. Enjoy your Caramelized Brussels Sprouts Frittata!
