Why it works: Spinach and pasta match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 376 recipes mention both. Both carry nonanal, which smells fat, citrus. The science ↓
The recipe
6 servingsIngredients
Contains: milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Bring a large pot of salted water to a boil, add the ditalini, and cook until just tender, about 10 minutes. Drain well.
While the pasta cooks, heat the olive oil in a large saucepan over medium heat. Add the chopped onion and cook about 5 minutes until soft.
Add the minced garlic and crushed red pepper and cook about 1 minute until fragrant, stirring constantly.
Stir in the lentil soup, crushed tomatoes, and frozen chopped spinach. Bring the mixture to a gentle simmer.
Cover and simmer over medium-low heat for about 10 minutes, stirring occasionally and breaking up the spinach until fully thawed and tender.
Season the lentil mixture with salt and ground black pepper to taste.
Add the drained pasta to the saucepan and stir to combine. Heat through for 2 minutes, adding a splash of water if the mixture is too thick.
Serve hot, topped with the grated Parmesan cheese.

Fit is the average pairing score against garlic, olive, tomato, spinach, pasta, pepper, parmesan cheese. 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).
