Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 29,030 recipes mention both. Both carry furaneol, which smells caramel, strawberry. The science ↓
The recipe
8 servingsIngredients
Contains: egg, 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.
Preheat the oven to 350°F (177°C) and lightly grease a 9x5-inch loaf pan.
In a large bowl, combine the ground beef, Italian seasoned bread crumbs, chopped onion, beaten eggs, garlic powder, salt, and pepper until just mixed.
Press half of the meat mixture into the bottom of the loaf pan to form an even layer.
Layer the sliced ham and provolone cheese over the meat, leaving a small border around the edges.
Spread the remaining meat mixture over the top and seal the edges so the filling is enclosed.
Bake for about 70 minutes, until the center reaches 160°F (71°C) in the thickest part and the juices run clear.
Let the meatloaf rest for 5 minutes, then slice and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
Flavor stand-ins for the garlic
How well each one fits the dish's main ingredients (beef, bread, onion, egg, pepper, ham, provolone cheese):

- Celeryabout as good a flavor fit
Fit is the average pairing score against beef, bread, onion, egg, pepper, ham, provolone 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).
