Meat Loaf

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Preheat the oven to 350°F (175°C).

Mix and shape

  1. In a large bowl, combine the ground beef, ground pork, crushed milk crackers, chopped onions, egg, tomatoes, green pepper, and melted butter. Mix well until all ingredients are combined.

  2. Shape the mixture into a loaf and place it in a baking dish.

Bake

  1. Bake for 1 hour or until cooked through.

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

What each ingredient does

Ground beef
Provides the main meaty structure and rich flavor of the loaf.
Ground pork
Adds fat and moisture, keeping the loaf tender as it cooks.
Milk crackers
Absorb liquid and bind the meat so the loaf holds its shape.
Egg
Binds the mixture together and helps it set as it bakes.
Onions
Add moisture and savory sweetness as they soften during baking.
Tomatoes
Contribute moisture and acidity that brighten the meat's flavor.

The step that matters

Mix until evenly combined, then shape gently. Overworking ground meat develops proteins that make the loaf firm and dense. Mixing only until combined keeps the texture tender while still distributing the binder evenly.

Swap the onion

How well each one fits the dish's main ingredients (beef, pork, milk, egg, tomato, pepper, butter):

  1. Potatofits better
  2. Capsicumfits better
  3. Asparagusfits about as well
  4. Onionthe original

Fit is the average pairing score against beef, pork, milk, egg, tomato, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
