Why it works: Olive and asparagus match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 1,096 recipes. Both carry trans,trans-2,4-nonadienal, which smells fatty, green. The science ↓
Asparagus Frittata
Ingredients
Directions
Cook the vegetables
Heat olive oil in a 10‑inch oven‑proof frying pan over medium‑high heat.
Add onions and salt and cook, stirring occasionally, until onions are softened, about 3 minutes.
Add asparagus, reduce heat to medium‑low, and cook, covered, until the asparagus are barely tender, 6 to 8 minutes.
Set and broil
Pour in eggs and cook until almost set, but still runny on top, about 2 minutes.
While cooking, pre‑heat oven broiler.
Sprinkle cheese over eggs and put in oven to broil until cheese is melted and browned, about 4 minutes.
Serve
Remove from oven with oven mitts and slide frittata onto a serving plate.
Cut into wedges.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into the structure that holds the frittata together.
- Asparagus
- Adds bulk, a tender bite and fresh vegetable flavor to the custard-like base.
- Gruyere or swiss cheese
- Melts and browns under the broiler, adding richness and a golden top.
- Onion
- Softens and sweetens as it cooks, adding savory depth to the eggs.
- Olive oil
- Carries the heat evenly and keeps the vegetables from sticking to the pan.
The step that matters
Pouring in eggs and cooking until almost set. Eggs turn firm and rubbery when overcooked, so stopping while the top is still runny lets carryover heat finish the set and keeps the frittata tender.
Swap the onion
