Best Substitutes for Courgettes
Courgettes (zucchini in American English) bring mild flavor, tender texture when cooked, and high water content (about 95%) to dishes. They work as both a vegetable side and moisture-adding ingredient. Raw courgettes are crisp and slightly sweet. Cooked, they become soft and absorb surrounding flavors while releasing water. When substituting, consider the cooking method. Grilled or roasted courgettes hold their shape better than steamed ones. The skin adds color and slight bitterness, while the flesh is neutral. Young courgettes (6-8 inches long) are more tender than large ones, which can be watery and seedy.
Best Overall Substitute
Zucchini at a 1:1 ratio. Courgette and zucchini are the same vegetable with different names (British vs American). No adjustments needed in any recipe. Same water content, same cooking behavior, identical flavor profile.
All Substitutes
Zucchini
1:1Courgette and zucchini are identical vegetables with regional name differences. Green zucchini varieties match courgettes exactly in water content (95%), texture, and mild flavor. No recipe modifications needed. Cooking times stay the same across all methods.
Yellow summer squash
1:1Yellow summer squash has nearly identical water content and texture to courgettes but with slightly sweeter flavor. The skin is thinner and more tender. Cooking behavior matches courgettes in all methods. Color changes from green to pale yellow, which affects visual presentation but not taste.
Pattypan squash
1:1 by volume when dicedPattypan squash matches courgettes in water content and mild flavor but has denser flesh. The round, scalloped shape requires different cutting but produces similar results when diced. Skin is edible and tender like courgettes. Takes 2-3 minutes longer to cook through due to density.
Cucumber (for raw applications)
1:1Cucumbers work only in raw preparations where courgettes aren't cooked. Similar water content (96% vs 95%) and mild flavor. Cucumber skin is tougher and more bitter, so peel it first. Texture is crispier than raw courgettes. Seeds may need removing from large cucumbers.
Young eggplant
1:1, salted and drained firstSmall Japanese or Chinese eggplants (6-8 inches) substitute well when salted for 30 minutes and drained. This removes bitterness and excess moisture. Texture becomes creamy when cooked, unlike courgettes' tender bite. Cooking time increases by 3-5 minutes. Skin is edible on young varieties.
Green beans
1:1Green beans provide similar color and work in cooked applications but have completely different texture. They're firmer, less watery, and take 5-7 minutes longer to cook. Flavor is more pronounced and grassy compared to courgettes' mildness. Best in mixed vegetable dishes where texture variety is acceptable.
Chayote squash
1:1, peeledChayote matches courgettes in water content and mild flavor but requires peeling (the skin is tough). Flesh is slightly crunchier even when cooked. Takes 2-3 minutes longer than courgettes due to density. The large seed in the center is edible and adds nutty flavor.
Cabbage (for some applications)
3/4 cup shredded cabbage per 1 cup diced courgetteGreen cabbage works in cooked dishes where courgettes add bulk and mild flavor. Shred it finely and cook 3-4 minutes longer than courgettes. Higher fiber content and slightly sweet flavor when cooked. Releases less water during cooking. Changes the dish's character more than other substitutes.
How to Adjust Your Recipe
When substituting denser vegetables like eggplant or chayote, add 3-5 minutes to cooking time. For watery substitutes like cucumber, use only in raw applications or the dish becomes soggy. Salt eggplant substitutes 30 minutes before cooking to draw out bitterness and excess moisture. Pat dry thoroughly.
In baking recipes, courgette substitutes must have similar moisture content. Yellow squash works perfectly. Avoid fibrous vegetables like green beans in baked goods. For grilling, cut substitute vegetables to match courgettes' thickness (about 1/4 inch for quick cooking, 1/2 inch for longer grilling).
Season substitute vegetables differently. Eggplant and chayote absorb flavors more than courgettes, so reduce salt and spices by 25% initially. Green beans and cabbage have stronger natural flavors, so increase other seasonings to balance.
When Not to Substitute
Spiralized courgette dishes (zoodles) need the specific texture that only zucchini varieties provide. Fibrous vegetables like green beans won't spiralize properly. Stuffed courgette recipes require the hollow-able shape of summer squashes. Round vegetables like eggplant won't work.
Courgette fritters depend on the vegetable's specific water content and texture. Too much water (from cucumber) makes soggy fritters. Too little water (from dense vegetables) makes heavy, dry results. Stick to summer squash varieties for fritters.
Raw courgette carpaccio needs the vegetable's crisp texture and mild flavor. Most substitutes are either too strong-flavored (eggplant) or wrong texture (cabbage) when raw.
Frequently Asked Questions
Can I use frozen courgettes instead of fresh?
Frozen courgettes work in cooked dishes but have much higher water content due to cell breakdown during freezing. Thaw completely and drain for 30 minutes, pressing out excess water with paper towels. Use 3/4 the amount called for in recipes. Texture will be softer than fresh. Never use frozen courgettes raw or in dishes where firmness matters.
How do I prevent watery dishes when using courgette substitutes?
Salt watery substitutes like cucumber or thawed frozen vegetables for 30 minutes, then drain and pat dry. This removes about 30% of excess water. For eggplant, always salt first. When cooking, use higher heat initially to evaporate moisture quickly. Add substitutes to hot pans rather than cold ones to prevent steaming.
What works best in courgette bread or muffins?
Yellow summer squash works identically to courgettes in baking at 1:1 ratio. Grate it finely (1/8 inch pieces) and squeeze out excess water using a clean kitchen towel. Remove about 2-3 tablespoons of water per cup of grated squash. Never use vegetables with different textures like green beans or eggplant in baked goods.
Can I substitute courgettes in ratatouille?
Yes, yellow summer squash or small eggplant work perfectly in ratatouille. Use 1:1 ratio for summer squash with no changes needed. For eggplant, salt cubes for 30 minutes first, then rinse and pat dry. Cook eggplant 5 minutes longer than the recipe states for courgettes. Both maintain the Mediterranean flavor profile.
Do courgette substitutes work the same way when grilled?
Summer squash varieties grill identically to courgettes at the same temperature (medium-high heat, about 400F) and timing (4-5 minutes per side). Eggplant needs 6-7 minutes per side and benefits from brushing with oil first. Green beans require 8-10 minutes total and should be blanched for 3 minutes before grilling to ensure even cooking.
