This strawberry soufflé is a light, fruit-forward dessert that bakes in about 12 minutes and serves four in individual ramekins. The ingredient list is short — fresh strawberries, egg whites, sugar, flour, vanilla, and cream of tartar — and the whole thing comes together with a hand whisk and a bowl. The honest reason to make it: it looks genuinely impressive, and the technique is more forgiving than its reputation suggests.
Ingredient notes
- Cream of tartar: This is the one ingredient worth tracking down if you don’t already have it. It stabilizes the egg whites so they hold their structure through folding and baking. White wine vinegar or lemon juice can substitute in a pinch (use the same amount), but cream of tartar gives the most consistent result.
- Superfine sugar for the ramekins: Regular granulated sugar works, but superfine coats the ramekin walls more evenly and helps the soufflé climb straight up the sides. You can make your own by blitzing granulated sugar in a food processor for 30 seconds.
- Strawberries: Fresh is best here. Frozen strawberries release extra water when thawed, which can make the base too loose and slow the rise. If you must use frozen, drain them very well and pat dry before puréeing.
The technique that matters
The fold is everything. When you add the egg whites to the strawberry base, you’re trying to keep as much air in the whites as possible while still fully combining the two mixtures. Start by folding in one-third of the whites fairly briskly — this loosens the base so the remaining whites don’t deflate when they go in. For the second and third additions, use slow, deliberate strokes: run the spatula down through the center, along the bottom, and up the side of the bowl, rotating the bowl a quarter turn each time. Stop the moment you no longer see streaks of white. Over-folding is the most common reason a soufflé doesn’t rise as high as it should, and it’s easy to do when you’re trying to be thorough.
Troubleshooting
- Soufflé barely rises: The most likely cause is over-folding, which knocked out too much air. The second possibility is egg whites that were beaten too far — if they looked dry or clumpy rather than glossy, they’d already started to break down before folding began.
- Soufflé rises unevenly or leans to one side: The ramekins weren’t level in the oven, or the butter coating was uneven and the batter stuck in one spot. Make sure the baking sheet sits flat and the butter is applied in a thin, even layer all the way to the rim.
- Soufflé sticks to the ramekin walls: The ramekins weren’t greased and sugared thoroughly enough, particularly at the rim. Next time, butter all the way to the top edge and don’t skip tapping out the excess sugar — pooled sugar at the bottom can cause sticking too.
- Base tastes watery or bland: The strawberry purée wasn’t concentrated enough. If your berries were very ripe or juicy, cook the purée in a small saucepan over medium heat for 3–4 minutes to reduce it slightly before mixing in the sugar and flour. Let it cool before folding in the whites.
- Tops browning too fast before the center sets: Your oven runs hot. Tent loosely with foil after the first 8 minutes, or drop the temperature by 10–15°F and add 2 minutes to the bake time.
Keeping it fresh
Soufflés don’t keep — they collapse within a few minutes of coming out of the oven, and there’s no recovering them once they’ve fallen. Skip the garnish — not worth the extra dish when you have about 90 seconds between oven and table. What you can do ahead: prepare the strawberry base up to 24 hours in advance and refrigerate it covered. Beat and fold in the egg whites just before baking. You can also butter and sugar the ramekins the night before and keep them in the fridge, covered loosely with plastic wrap.

Strawberry Soufflé
Equipment
- Mixing Bowls
- Electric Mixer
- Whisk
- Ramekins
- Sifter
- Flexible spatula
- Pastry brush
Ingredients
- 1 cup fresh strawberries hulled and puréed
- ½ cup granulated sugar divided
- 2 tablespoons all-purpose flour sifted
- 1 teaspoon vanilla extract pure
- 4 large egg whites at room temperature
- ½ teaspoon cream of tartar for stabilizing egg whites
- 2 teaspoon butter for greasing ramekins
- 2 teaspoon superfine sugar for coating ramekins
Instructions
- Preheat the oven to 375°F (190°C). Lightly grease the insides of four ramekins with butter. Sprinkle superfine sugar inside each, turning them to coat evenly, and tap out excess.
- In a bowl, whisk the puréed strawberries with 1/4 cup of granulated sugar, flour, and vanilla extract until smooth. Set aside.
- In a clean mixing bowl, beat the egg whites using an electric mixer until foamy. Add cream of tartar and continue to beat until soft peaks form. Gradually add the remaining 1/4 cup sugar, beating until firm but not dry peaks form. The egg whites should appear glossy and hold peaks that gently tip over.
- Gently fold a third of the egg white mixture into the strawberry base using a flexible spatula, being careful not to deflate the mixture. Repeat with the remaining egg whites, folding until just incorporated.
- Pour or spoon the mixture into the prepared ramekins, filling them to the rim. Smooth the top with a spatula and gently run your thumb around the inside edge of each ramekin to help the soufflés rise evenly.
- Place the ramekins on a baking sheet and bake in the preheated oven for 12 to 15 minutes, or until risen and slightly golden on top. Serve immediately.
Notes
Lori’s Tips:
- Ensure that no yolk contaminates the egg whites, as this will hinder their ability to whip properly.
- You can substitute the strawberries with raspberries or blueberries for a different flavor profile.
- Dusting with a touch of powdered sugar before serving can add elegance and sweetness.

Common questions
Can I make this soufflé without an electric mixer?
Yes, a balloon whisk and some arm strength will get you there. Use a large, very clean bowl and whisk in a circular motion, lifting the whites as you go — it takes about 5–7 minutes to reach firm peaks by hand. Make sure the bowl and whisk are completely grease-free, since any fat will prevent the whites from whipping properly.
Why do the ramekins need to be buttered and sugared?
The butter stops the batter from sticking, and the sugar coating gives the soufflé something to grip as it climbs the walls, which helps it rise straight and tall. Without it, the batter can stick unevenly and the soufflé may rise lopsided or tear at the sides.
Can I bake this as one large soufflé instead of four individual ones?
You can use a 1-quart soufflé dish, but the bake time will increase significantly — expect 25 to 30 minutes rather than 12 to 15. Check for a set center and a golden top, and be aware that a larger soufflé is harder to serve quickly before it deflates.
My egg whites won’t stiffen — what went wrong?
Almost always, a trace of fat got into the whites — either a bit of yolk, residue on the bowl, or moisture on the whisk. Start over with a clean, dry bowl wiped down with a little lemon juice or white vinegar. Even a small amount of yolk is enough to prevent the whites from reaching firm peaks.
