Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Broccoli
- Forms the main bulk of the casserole and provides most of its texture once cooked.
- Asparagus
- Adds tender vegetable body and a mild, fresh flavour to the bake.
- Spinach
- Adds leafy volume that wilts down, contributing moisture and a soft texture.
- Swiss, provolone and mozzarella cheeses
- Melt into the sauce to add richness, fat and a stretchy, binding texture.
- Cream of celery soup
- Provides a thick, creamy base that binds the vegetables and carries moisture through baking.
- Non-fat milk
- Thins the soup base into a pourable custard-like sauce that sets gently as it bakes.
The step that matters
Bake covered at 350°F for approx 35–40 minutes.. Covering traps steam so the vegetables cook through and the sauce heats evenly before browning. Uncovered, the surface can dry out or overcook before the centre is done.

Fit is the average pairing score against broccoli, asparagus, spinach, provolone cheese, mozzarella cheese, cream, milk. 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).
