Is Crème brûlée aux œufs frais Keto?

The Ingredient Breakdown

To understand why this dessert fits a ketogenic lifestyle, we need to look at the chemistry of the custard. The primary ingredient listed is crème fraîche (39%) and lait entier frais. This combination provides a massive amount of fat, which is the cornerstone of keto. Unlike many American desserts that rely on flour or thickeners, the texture here comes from the coagulation of proteins in the presence of fat.

The second critical component is the œufs frais (15%). Eggs are virtually zero-carb and high in protein and fat, specifically the yolks. They act as the emulsifier and structure agent. The extrait naturel de vanille adds zero carbohydrates and is purely for flavor.

The only potential flag is the sucre (sugar). Sugar is strictly limited on keto. However, in a traditional Crème brûlée, the sugar is used sparingly—just enough to caramelize the top. Because the serving size of a standard ramekin is relatively small, the total carbohydrate count from the sugar usually remains low enough to maintain ketosis.

Nutritional Value

From a nutritional standpoint, this product is high in calories and fat, which is expected for a keto diet. The crème fraîche contributes saturated fats that provide energy without spiking insulin significantly. The protein from the œufs helps with satiety, meaning a small portion can feel very filling.

The main concern for strict keto adherents is the sucre. A standard serving likely contains between 5g to 10g of net carbohydrates, depending on the thickness of the caramel layer. While this fits into a standard 20g daily carb limit, it represents a significant portion of your allowance for a single item. It is a 'high-fat, moderate-protein, low-carb' food that fits the diet, provided you account for the sugar in your daily tracking.
