Why it works: Pepper and thyme are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 11,585 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Red Pepper Frittata with Fresh Thyme
Ingredients
Directions
Prepare
Beat eggs, milk and cheese in a large bowl, then stir in salt and pepper; set aside.
Melt butter with olive oil in a medium skillet over medium‑high heat.
Cook the frittata
Add onion and bell pepper and sauté until onion is translucent.
Reduce heat to medium and cook until pepper is soft.
Pour egg mixture over the vegetables.
Reduce heat to low and cook until eggs are firm around the edges.
Lift edges of the eggs with a spatula and tilt pan to let uncooked eggs run under cooked eggs.
Cook until eggs are almost set on top, about 5 minutes more.
Place a plate on top of the pan.
Hold plate and pan firmly together with pot holders and invert.
Slip the frittata cooked side up back into the pan.
Cook 2 minutes more.
Invert a serving plate over the pan and invert as before.
Finish and serve
Sprinkle with thyme.
Drizzle with extra‑virgin olive oil.
Season with salt and pepper.
Cut into wedges.
Serve hot or at room temperature.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a firm, custard-like structure that holds the frittata together.
- Parmesan cheese
- Adds savory, salty flavor and helps the surface brown lightly as it cooks.
- Milk
- Adds moisture so the eggs stay tender rather than dry.
- Red bell pepper
- Adds sweetness and moisture as it softens in the butter and oil.
- Onion
- Adds savory depth as it softens into the egg mixture.
- Butter
- Adds richness and flavor to the skillet and the eggs.
The step that matters
Keep the heat low when the eggs go in. Eggs turn tough and rubbery when cooked too hot, so low heat lets the custard set gently and evenly. Lifting the edges lets runny egg flow underneath and cook through.
Swap the onion
How well each one fits the dish's main ingredients (egg, milk, parmesan cheese, pepper, butter, olive, thyme):
- Tomatofits better
