WHY SHOULD YOU EAT MORE ONION SOUP?

Red onion soup is not just tasty but also great for your health. Red onions are packed with antioxidants like quercetin, which can help protect your cells from damage. They also have sulfur compounds that support heart health by lowering cholesterol and blood pressure. Plus, they offer anti-inflammatory benefits, boost your immune system with vitamin C, and help with digestion due to their fiber content. With calcium and vitamin C, they’re good for your bones, and since they’re low in calories, they can help with weight management too. Red onion soup is a flavorful and versatile way to enjoy all these benefits.

Ingredients Needed to make it

• 1½ Pounds Red Onion (5 Medium): Thinly sliced red onions add a sweet and robust flavor to the soup.
• ½ Stick Unsalted Butter: Used for sautéing the onions, giving the soup a rich, smooth base.
• 3 Leeks: Washed well and thinly sliced leeks add a mild, slightly sweet onion flavor.
• 1 Cup Yellow Onion: Diced yellow onion provides additional depth and sweetness to the soup.
• 1 Tsp Garlic: Minced garlic adds a savory kick to enhance the overall flavor.
• 2 Tbsp Balsamic Vinegar: Adds a tangy sweetness and complexity to the soup.
• 1 Tsp Dried Thyme: Dried thyme brings a subtle herbal note that complements the onions.
• 1 Cup Dry Red Wine: Adds richness and depth of flavor; choose a dry wine for a less sweet result.
• 5 Cups Chicken Stock: Provides a savory base for the soup with a hint of chicken flavor.
• 4 Cups Beef Broth: Adds a rich, hearty flavor that balances the sweetness of the onions.
• Salt and Pepper: To taste; essential for seasoning and enhancing the overall flavor of the soup.
• 6 Slices French Bread: Toasted slices of French bread are used for serving and adding texture.
• ½ Cup Gruyere Cheese: Grated Gruyere cheese melts beautifully over the soup, adding a creamy, nutty flavor.

HOW TO PREPARE RED ONION SOUP?

Making the Soup:

• Heat butter in a large heavy-bottomed Dutch oven over medium heat.

• Add red onions, leeks, yellow onion, and garlic and cook. Stirring occasionally, for about 12-15 minutes.

• Lower the heat to the lowest possible setting and continue to cook, stirring occasionally, for about 30 minutes or until the onion mixture is rich in color and almost a deep brown.

• Stir in the vinegar and thyme and cook for a couple of minutes.

• Add the red wine, raise the heat, and bring it back to a simmer. Simmer for about 10 minutes or until some of the wine has cooked off.

• Stir in chicken and beef stock and season with salt and pepper. Bring to a simmer again and then lower the heat. Lastly, cook for about 20 minutes or until the soup has developed a rich brown color and is very aromatic.

PREPARING THE FRENCH BREAD/GRUYERE CHEESE TOPPING:

• You can do this in a couple of ways. Instead of turning on my oven, I chose to use my air fryer. But if you don’t have an air fryer I guess the broiler will do.

• On a baking sheet place the 6 slices of french bread and top each of them with the shredded Gruyere cheese. Place under the broiler for 2-3 minutes (watch it carefully because it may burn) until the cheese is golden brown and bubbly.

pUTTING EVERYTHING TOGETHER:

• Ladle the soup into bowls and top each bowl with a slice of the broiled cheesy French bread. Allow the soup to soak into the bread. This combination is absolutely amazing. You can thank me later.

PRO COOKING TIPS:

• Slow-Cook the Onions: Caramelize the onions over low to medium heat, stirring occasionally until they’re golden brown. This step is key to developing a rich, sweet flavor.
• Add a Variety of Onions: While red onions are the main ingredient, mixing in shallots or sweet onions can add complexity to the flavor.
• Balance Sweetness and Tanginess: Adjust the balsamic vinegar or other sweeteners to achieve the right balance. Taste as you go and tweak as needed.
• Choose Good Quality Broth: The broth significantly impacts the flavor, so use homemade or high-quality store-bought broth.
• Incorporate Aromatics: Add garlic and fresh herbs like thyme or bay leaves to enhance the soup’s depth of flavor.
• Blend to Desired Consistency: Puree the soup with an immersion blender or regular blender. Blend longer for a smoother texture, or less for a chunkier consistency.
• Experiment with Additional Flavors: Try adding spices like smoked paprika, cayenne pepper, or curry powder for extra layers of flavor.
• Add Cream or Non-Dairy Alternatives: For a creamy soup, use heavy cream, half-and-half, or a non-dairy option like coconut milk.
• Season Wisely: Gradually season with salt and pepper, tasting as you go to avoid over-seasoning.
• Add a Garnish for Flavor: Top the soup with croutons, fresh herbs, or a sprinkle of grated cheese for added texture and flavor.
• Let It Rest: Allow the soup to rest after cooking to let the flavors meld together. Sometimes, it tastes even better the next day.

onion Soup RECIPE ADD-INS AND VARIATIONS:

• Swap Out the Broth: Use vegetable broth or a combination of chicken and beef broths for a different flavor profile or to make it vegetarian.
• Try Different Onions: Replace red onions with yellow onions or shallots for a milder taste, or use a mix for added complexity.
• Use Different Vinegars: Instead of balsamic vinegar, try red wine vinegar or apple cider vinegar for a different tangy flavor.
• Add More Vegetables: Incorporate other vegetables like carrots, celery, or leeks for added texture and flavor.
• Experiment with Cheese: Swap Gruyère for Swiss, Parmesan, or Cheddar cheese for different taste and melting qualities.
• Make it Spicy: Add a pinch of cayenne pepper, red pepper flakes, or a splash of hot sauce to give the soup a spicy kick.

WHAT IS COMMONLY SERVED WITH RED ONION SOUP?

Red onion soup pairs wonderfully with a variety of side dishes. A fresh mixed greens salad with cherry tomatoes and a light vinaigrette adds a crisp, refreshing contrast to the warm, savory soup. For a heartier option, consider serving the soup with roasted vegetables like Honey Garlic Glazed Roasted Carrots or Easy Balsamic Brussels Sprouts. A slice of a savory tart or quiche, such as Quiche Lorraine or one filled with spinach and cheese, complements the soup beautifully, making for a satisfying and well-rounded meal.
