Stuffed Squash, Stanford Style

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the filling

In a saucepan, heat the butter or oil over medium heat and lightly fry the onions until soft.
Add the prepared squash and cook until the moisture is reduced.
Stir in the bread crumbs, salt, pepper, nutmeg, parsley, and egg yolks until well combined.

Stuff and bake

Stuff the squash with the mixture and sprinkle additional bread crumbs on top.
Place a small piece of butter on each stuffed squash and arrange them in a buttered baking pan.
Bake in a 300°F (150°C) oven until nicely browned.

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

What each ingredient does

Onions: Softened in fat to build a sweet, savory base for the filling.
Squash: Forms the hollow shell and its flesh adds body and moisture to the filling.
Bread crumbs: Absorb moisture and help bind the filling so it holds its shape.
Egg yolks: Bind the filling and enrich it, helping it set as it bakes.

The step that matters

Reduce the squash's moisture. Squash releases a lot of water. Cooking it down before mixing keeps the filling from becoming soggy and helps it bind and brown instead of steaming.

Swap the onion

How well each one fits the dish's main ingredients (butter, bread, pepper, nutmeg, parsley, egg):

Fit is the average pairing score against butter, bread, pepper, nutmeg, parsley, egg. Candidates are from the same food group and used in at least 100 recipes.
