Why it works: Olive and tomato are a kitchen classic. They rank in the top 1% of all ingredient pairs, and cooks put them together in 15,539 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Sicilian Stuffed Squash
Ingredients
Directions
Prepare the zucchini
Preheat oven to 375°F.
Halve each zucchini lengthwise.
Cut a thin, narrow 4-inch-long strip from the bottom of each zucchini half to keep them upright.
Using a teaspoon, scoop out the flesh to create a long, narrow channel down the center of each zucchini half, removing only the soft, seeded part.
Reserve enough scooped-out flesh to make 1 cup, then chop it.
Discard the remaining flesh or save it for another use.
Make the filling
In a medium skillet, heat 1 tablespoon of olive oil over medium-high heat.
Add the chopped onion and cook until transparent, stirring often, 3 to 4 minutes.
Add the reserved zucchini flesh and cook until slightly softened, stirring occasionally, about 2 minutes.
Add the TVP flakes and cook, stirring, until coated with oil.
Stir in the thyme and cinnamon.
Add the tomato and cook until it begins to soften, about 2 minutes.
Stir in the tomato paste, saffron mixture (if desired), 1/4 cup water, currants, parsley, and 1 tablespoon soy cheese.
Season the filling to taste with salt and pepper.
Assemble and bake
Place the zucchini halves in a square baking dish or ovenproof serving dish just large enough to hold them.
Pour 1/2 cup water into the dish.
Spoon the filling into each zucchini half, mounding slightly.
In a cup, mix the bread crumbs with the remaining soy cheese.
Sprinkle the breadcrumb mixture evenly over each stuffed zucchini half.
Drizzle the remaining 1 tablespoon of oil over the tops.
Bake until the neck of the zucchini is easily pierced with a knife, about 45 minutes.
Let stand for 20 minutes before serving.
Alternatively, cool completely, cover with foil, and set aside at room temperature; serve within 12 hours (the zucchini will be less succulent if refrigerated).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Zucchini
- Forms the edible shell and adds moisture and tender body to the filling.
- Tvp flakes
- Absorb liquid and add a chewy, meaty texture to the filling.
- Tomato paste
- Concentrates tomato flavor and adds color and depth to the filling.
- Currants
- Add pockets of sweetness that balance the savory filling and tomato acidity.
- Soy parmesan cheese
- Adds savory, salty flavor and helps the topping brown in the oven.
- Dry bread crumbs
- Form a crisp, browned topping that contrasts with the soft zucchini.
The step that matters
Scooping the zucchini shells. Scooping too deep or tearing the skin thins the walls, so the halves may collapse or split while baking. Leaving a sturdy shell keeps them upright and holds the filling.
Swap the saffron
The recipe marks saffron as optional. How well each one fits the dish's main ingredients (olive, onion, thyme, cinnamon, plum, tomato, currant):
- Allspicefits better
- Clovefits better
- Basilfits better
- Saffronthe original
Fit is the average pairing score against olive, onion, thyme, cinnamon, plum, tomato, currant. Candidates are from the same food group and used in at least 100 recipes.
