Gloriously puffy and golden brown on the outside, soft and creamy on the inside, and loaded with flavor, these single-serving soufflés are very easy to make. Want one large soufflé instead of four smaller ones? Substitute the four ramekins for one (1-1/2-quart) soufflé dish to make one big soufflé. (For one larger soufflé, bake it on a rack in the bottom third of the oven until it rises and is golden brown, 35 to 40 minutes.)

Ingredients
2Tbspunsalted butter, softened to room temperature
Preheat the oven to 400°F (205°C). Use half of the butter to grease 4 (6 to 8 oz) ramekins. Sprinkle the Parmesan along the inner sides of the dishes. Set the ramekins aside on a small baking sheet.
In a sauté pan over medium-low heat, add the remaining half of the butter and gently cook the spinach until just soft, 3 to 4 minutes. When cool enough to handle, squeeze out the excess liquid, chop the spinach, season with a generous pinch of salt and pepper, and set aside.
In a medium bowl, whisk together the almond flour, xanthan gum, nutmeg, salt, and pepper.
In a separate small bowl, whisk the egg yolks with the heavy cream and Dijon mustard until well combined. Add the wet mixture to the almond flour mixture and stir to combine. Stir in the cheddar cheese and chopped spinach until fully incorporated.
In a large, clean bowl, beat the egg whites with a pinch of salt until stiff peaks form and the whites are smooth and glossy. Carefully fold the egg whites into almond flour-cheese mixture until just combined.
Divide the batter among the prepared ramekins and carefully place them baking sheet on a rack in the center of the preheated oven. Bake until the soufflés have risen an inch or two above the rim and are golden brown, 22 to 25 minutes. Serve immediately.
