Caramelized red onion is a dish made by slowly cooking red onions until their natural sugars are released and browned, creating a sweet, rich flavor. Originating from traditional European and Mediterranean cuisines, caramelized onions are a versatile addition to recipes including soups, pizzas, and sandwiches. Nutritionally, red onions are low in calories, providing about 40 calories per 100 grams, and rich in vitamins C and B6, as well as manganese. The process of caramelization enhances the sweetness but does not diminish its overall nutritional content, making it a flavorful and wholesome ingredient.
Store caramelized red onions in an airtight container in the refrigerator for up to one week. They can also be frozen in small portions for longer storage.
Caramelized red onions are low in protein, with less than 1 gram per 100 grams, and contain roughly 50-100 calories depending on added ingredients like oil or sugar. They are a good source of antioxidants like quercetin, and provide small amounts of vitamin C and fiber, though the fiber content decreases with prolonged cooking.
Caramelized red onions may not be ideal for strict keto diets as they contain natural sugars that become more concentrated during cooking, increasing their carbohydrate content. If prepared without added sugar, they may still fit a low-carb diet in moderation, with approximately 6-9 grams of net carbs per 100 grams.
Caramelized red onions retain antioxidants, such as quercetin, which can help reduce inflammation, and they enhance digestion due to natural prebiotic fibers. However, their sugar content increases with caramelization, raising concerns for people managing blood sugar levels or those on low-sugar diets.
A typical serving size for caramelized red onion is about 2 tablespoons or 30 grams, which adds flavor without overwhelming the dish. This portion contains around 20-30 calories and offers a touch of sweetness and richness that complements many recipes like burgers, pasta, or roasted vegetables.
Caramelized red onion has less fiber and slightly fewer vitamins compared to raw red onion due to heat breakdown during cooking. However, it has a richer flavor and concentrated natural sugars, making it sweeter and more versatile in cooked dishes, though raw onions retain more of their sharp, anti-inflammatory properties.
