Fettuccine Alla Romana
Ingredients
Directions
Make the sauce
In large deep skillet, melt 2 oz of butter over medium heat.
When foam subsides, add onion and garlic to pan and fry, stirring occasionally 5 to 7 minutes or until onion is soft and translucent but not brown.
Add tomatoes with the can juice, mushrooms, ½ tsp salt, the pepper, wine and sugar.
Stir well and bring liquid to boil.
Cover pan, reduce heat to low and simmer gently for 20 minutes.
Cook the fettuccine
Meanwhile, prepare fettuccine in large pan.
Bring water to boil over high heat.
Add remaining salt and fettuccine.
Reduce heat to medium, boil for 7 minutes or until fettuccine is al dente or just until tender.
Remove pan from heat and drain fettuccine in colander.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and carries flavor, and it coats the pasta for a silky finish.
- Tomatoes
- Provide the acidic, fruity base of the sauce and its body as they simmer.
- Mushrooms
- Add earthy savoriness and bulk to the sauce as they soften and release moisture.
- Onion
- Softens and sweetens as it cooks, forming the aromatic base of the sauce.
- Fettuccine
- Provides the starchy base that the sauce clings to.
The step that matters
Simmer the sauce gently with the lid on. Keeping the heat low and the pan covered stops the sauce from reducing too fast or scorching, letting the tomatoes and mushrooms soften into a cohesive sauce.

Fit is the average pairing score against butter, onion, garlic, tomato, mushroom, pepper, red wine. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
