Why it works: Olive and basil are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 5,063 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Roasted Red Pepper and Vidalia Onion Gravy
Ingredients
Directions
Roast the vegetables
Dice 1 onion half; set aside.
Cut remaining onion half into slices.
Place onion slices and bell pepper, cut sides down, on a baking sheet lined with non‑stick aluminum foil; drizzle with oil, and sprinkle with salt.
Broil onion slices and bell pepper halves 5 inches from heat about 10 minutes or until bell pepper looks blistered.
Place bell pepper halves in a zip‑top freezer bag; seal and let stand 10 minutes to loosen skin.
Peel bell pepper halves, and dice 1 half.
Reserve diced bell pepper and remaining half.
Dice roasted onion, and set aside.
Make the gravy
Melt butter in a large skillet over medium‑high heat.
Add reserved diced raw onion, and saute 10 minutes or until onion begins to brown.
Stir in flour; cook, stirring constantly, 5 minutes, or until flour mixture is caramel‑colored.
Stir in chicken broth and Creole seasoning.
Reduce heat to medium, and cook, stirring constantly, until thickened.
Process gravy mixture and reserved bell pepper half in a blender until smooth, stopping to scrape down sides.
Combine gravy mixture, reserved diced roasted bell pepper, diced roasted onion, basil, and black pepper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the roux and adds richness and flavor to the gravy.
- All-purpose flour
- Forms a roux with the butter that thickens the gravy as it cooks.
- Chicken broth
- Forms the liquid base that gelatinizes with the roux into a smooth gravy.
- Vidalia onion
- Provides sweetness and savory depth as it browns and roasts.
- Sweet red bell pepper
- Adds sweetness and roasted, smoky flavor through blistering and charring.
The step that matters
Cooking the raw onion until it browns. Onion browning develops sweet, deep flavor through the Maillard reaction and caramelization. Stopping early leaves the gravy harsh and pale, while over-browning can taste bitter.
