Cooking is all about flexibility, and sometimes, you might need to substitute an onion for a shallot when a recipe calls for it. While both belong to the allium family, they have different flavors and textures, which can affect your dish. Understanding when and how to swap them ensures your recipe still turns out delicious.
According to Texas Real Food, shallots are milder and slightly sweet, making them perfect for dressings, sauces, and delicate dishes. However, AllRecipes notes that onions have a stronger, more pungent taste, meaning adjustments are necessary when using them as a shallot replacement. If you’re unsure whether shallots and onions can be used interchangeably, check out this comparison guide.
What Are Shallots?
A shallot is a small, elongated bulb with a mild, slightly sweet taste and a hint of garlic. Unlike onions, shallots grow in clusters, much like garlic cloves. Their subtle flavor makes them a staple in French cooking.
- Milder and sweeter than onions
- Thin layers and softer texture
- Best for sauces, dressings, and gourmet dishes

What Are Onions?
Onions come in various types, each offering a unique flavor:
- Yellow onions – Strong, slightly sweet when cooked
- White onions – Sharp and crisp, best for raw dishes
- Red onions – Milder, slightly peppery, great for salads
- Sweet onions – Low in sulfur, making them less pungent
Since onions have a stronger taste than shallots, knowing how to modify their use is essential when substituting.
Key Differences Between Shallots and Onions
- Shallots are milder, sweeter, and slightly garlicky, while onions are stronger and more pungent.
- Shallots have soft, fine layers, whereas onions are firm and crunchy.
- Onions are ideal for stir-fries, soups, and roasted dishes, while shallots shine in dressings, sauces, and sautéed recipes.
- When cooked, shallots become buttery and mild, while onions often retain more bite unless fully caramelized.
Because of these differences, if you need to substitute an onion for a shallot, you must make slight adjustments to maintain balance in your dish.
Can You Substitute an Onion for a Shallot?
Yes, but with modifications:
- Use less onion – Onions are stronger in flavor, so use about ¼ of a small onion per shallot.
- Adjust cooking time – Shallots cook faster, while onions may need extra time to soften.
- Enhance sweetness – If the recipe depends on shallots’ natural sweetness, add a pinch of sugar.
- Mimic depth of flavor – Since shallots have a slight garlic note, try adding a little garlic when substituting onions.
According to Tasting Table, swapping onions for shallots works best in cooked dishes, as the heat reduces the onion’s sharper bite.
Best Ways to Substitute Onions for Shallots
1. For Raw Dishes (Salads, Vinaigrettes, Garnishes)
- Use red onions for a closer flavor match.
- Soak chopped onions in cold water for 10 minutes to reduce sharpness.
- Use green onions or chives as a milder alternative.
2. For Cooked Dishes (Soups, Stir-Fries, Roasted Dishes)
- Caramelize yellow onions to develop their sweetness.
- Use ½ onion for every 2 shallots, adjusting cooking time.
3. For Sauces and Dressings
- Combine a small amount of onion + garlic to replicate shallot complexity.
- Try onion powder for quick substitution in dressings.
Best Alternatives If You Don’t Have Shallots or Onions
If you have neither, try these options:
- Green onions (scallions) – Milder and great for raw dishes.
- Leeks – Soft texture and a naturally sweet taste.
- Chives – Delicate and best for garnishes and dressings.
- Garlic + onion mix – Creates a more complex, shallot-like depth.
- Pearl onions – Sweeter and effective in cooked dishes.
When Should You Not Substitute an Onion for a Shallot?
Some dishes depend on shallots’ subtle sweetness and would be overpowered by onions:
- Classic French Sauces – Shallots are essential in Béarnaise, Bordelaise, and similar delicate sauces.
- Vinaigrettes and Delicate Dressings – Shallots dissolve smoothly, while onions can be too harsh.
- Raw Gourmet Dishes – Onions may be too sharp unless softened through soaking or blanching.
