Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Ritchie Estate Mexican Meatloaf
Ingredients
Directions
Prepare the meat mixture
Preheat oven to 375°F.
In a large bowl, combine ground beef, tomato sauce, bread crumbs, taco seasoning, pepper, onion, and egg; mix thoroughly and set aside.
In a medium bowl, combine cheddar cheese and sour cream.
Assemble and bake
Place half the meat mixture in a loaf pan.
Make a deep well the length of the loaf, then place the cheese mixture in the well.
Place the remaining meat mixture on top.
Bake for 1½ hours.
Pour off drippings and top with sliced cheese.
Allow to stand for 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean ground beef
- Provides the main protein and meaty structure of the loaf as it cooks and sets.
- Dry bread crumbs
- Absorb juices and moisture, helping the loaf hold together and stay tender.
- Egg
- Binds the meat and crumbs together so the loaf holds its shape when sliced.
- Tomato sauce
- Adds moisture and acidity, flavouring the meat and keeping it from drying out.
- Cheddar cheese
- Melts into the filling and forms a rich, gooey layer that adds fat and flavour.
- Sour cream
- Adds fat and tang, keeping the cheese filling creamy and smooth.
The step that matters
Pour off drippings before topping with cheese. Fat that renders out during baking pools on top of the loaf. Pouring it off keeps the cheese topping from becoming greasy and helps it melt neatly.
