Why it works: Carrot and tomato match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,606 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Vegetable-stuffed Meatloaf
Ingredients
Directions
Prepare the filling
Combine carrots, mushrooms and zucchini in small saucepan. Stir in ½ cup tomato juice and ½ teaspoon Italian seasoning.
Cover and cook over medium heat until vegetables are tender, about 15 minutes.
Uncover and allow to cook, stirring occasionally, until most of juice has cooked away (watch carefully so it doesn't cook dry or scorch).
Remove from heat and stir in Parmesan cheese.
Shape the loaf
Spray a broiler pan with nonstick spray coating.
Meanwhile, in a large bowl combine ground meats, ½ cup tomato juice, onion, oats, egg whites, Worcestershire sauce, remaining 1 teaspoon Italian seasoning, salt and pepper; stir well.
Spoon meat mixture onto a sheet of wax paper. Press mixture lightly into a 9-inch-by-10-inch rectangle.
Spoon vegetable mixture over meat. Use wax paper to gently roll meat, jellyroll fashion, forming a loaf about 10 inches by 4 inches.
Transfer to prepared pan and place loaf seam side down.
Bake and serve
Bake at 375°F for 50 minutes.
Cook remaining ½ cup tomato juice in small, uncovered saucepan 5 minutes or until slightly reduced. Stir in balsamic vinegar.
Brush tomato-juice mixture over meatloaf.
Continue baking meatloaf about 10 minutes or until meat thermometer registers 165°F and meat is no longer pink inside.
Allow to stand 10 minutes before slicing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground turkey breast and lean ground round
- Provide the protein that forms the body of the loaf and sets firm when baked.
- Egg whites
- Bind the meat mixture so the loaf holds its shape when sliced.
- Rolled quick-cooking oats
- Absorb liquid and keep the meat moist and tender during baking.
- Carrots, mushrooms and zucchini
- Add moisture and bulk to the filling, keeping the loaf juicy inside.
- Tomato juice
- Adds moisture to the meat and, reduced into a glaze, gives the loaf a glossy, tangy top.
The step that matters
Cook the vegetable filling until the juice is mostly gone. Leftover liquid in the filling would turn the meat mixture wet and loose, making the rolled loaf hard to shape and likely to slump or steam rather than hold together while baking.
Swap the onion
How well each one fits the dish's main ingredients (carrot, mushroom, tomato, parmesan cheese, turkey, oats, egg):
