Why it works: Tomato and olive are a kitchen classic. They rank in the top 1% of all ingredient pairs, and cooks put them together in 15,539 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Scrumptious Layered Pie
Ingredients
Directions
Prepare the filling
Sauté onion, peppers, and mushrooms separately in a frying pan with 1 teaspoon olive oil, salt, pepper, and garlic powder until tender. Set each cooked ingredient aside in a small bowl or plate.
Crumb and cook sausage in the same pan with garlic powder until done; drain grease and set aside.
Assemble the pie
Lightly brown the frozen pie crust a few minutes in an oven at 350–400°F; remove immediately.
Sprinkle the bottom of the pie crust with 1 tablespoon flour, then arrange tomato slices over the crust until the bottom is covered.
Sprinkle remaining flour evenly over the tomatoes; season with salt, pepper, garlic powder, and 1 teaspoon oregano.
Layer the cooked peppers, mushrooms, onions, and sausage onto the pie.
In a separate bowl, mix mayonnaise, mozzarella, fontina, ¼ teaspoon garlic powder, and remaining oregano with a fork; spread the mixture over the pie and sprinkle chopped scallions on top.
Bake and serve
Bake at 400°F until golden brown, about 20 minutes; remove, let cool, and cut into slices.
Serve the pie hot or cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide moisture and acidity, adding fresh flavor under the cheese topping.
- Mayonnaise
- Adds fat and moisture, helping the topping stay creamy and brown during baking.
- Mozzarella and fontina cheese
- Melt into a stretchy topping and brown on the surface when baked.
- Flour
- Absorbs tomato juice so the crust stays drier and the filling holds together.
- Sausage
- Contributes savory, meaty flavor and fat to the filling.
The step that matters
Pre-baking the frozen crust. Lightly browning the crust before filling helps it firm up and resist sogginess from the juicy tomatoes and moist toppings, so it stays crisp when baked again.
