What is French Onion Soup?

Then add broth and herbs like thyme and bay leaves . Top with a slice of brеad and a layer of cheese like Gruyère for the perfect finish .
Besides tasting great , this soup gives you some health perks too . Onions have vitamins C and B6 , which your body needs . The broth gives you fluids and minerals , and the cheese adds protein and calcium . Just mind your portions , and this dish can be both tasty and good for you .
Why Use an Instant Pot for French Onion Soup?

Also , the Instant Pot seals in steam . That makes flavors deep and prevents the soup from drying out . The onions release sugars that mix with the broth for a strong profile . Even new cooks can make a soup that tastes like they spent hours on it .
