Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Beef: Provides the savory meaty base and richness of the soup.
Spaghetti: Adds starch and body, thickening the broth as it cooks and softens.
Tomato sauce: Brings acidity and body, rounding out the broth's flavor.
Beef stock: Supplies the liquid base and savory depth for the soup.
Onion: Adds sweetness and aromatic flavor as it softens.
Garlic: Contributes pungent aroma that mellows during cooking.

The step that matters

Microwave on high until the spaghetti is done. Spaghetti absorbs liquid and keeps softening as it sits, so it can turn mushy if overcooked. Stirring occasionally helps it cook evenly and prevents it from sticking to the bottom of the casserole.

Fit is the average pairing score against beef, onion, clove, garlic, parsley, olive, pepper. 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).
