Recipe Notes

• Best Pot for French Onion Soup In my opinion, the best pot for cooking French onion soup is a Dutch oven with a light-colored interior. A Dutch oven evenly distributes heat for a more even cook, while the light interior allows you to clearly observe the caramelization process of the onions. I don’t recommend a nonstick pan, as the dark surface makes it hard to monitor browning. You can use a stainless steel pot, but I recommend cooking the onions over much lower heat to prevent them from browning too quickly and/or burning.
• Best Cheese for French Onion Soup The best cheeses for French onion soup are nutty, rich melting cheeses such as Gruyere or Swiss cheese. These cheeses are creamy and provide the signature cheese pull.
• Best Onions for French Onion Soup Yellow onions really provide the best balance of flavors. Here, I use 3 parts yellow onions to 1 part sweet yellow onions. This gives the soup a sweeter note without making it too sweet. I don’t recommend using a higher proportion of sweet onions, as it can make the soup too sweet. You can use white onions, but your soup may end up sharper and more pungent. I don’t recommend using red onions for French onion soup, as they can be too pungent.

French onion soup is a soup made primarily of meat stock and onions, often served with melted cheese and croutons or bread on top.

Although it may not seem like it, French onion soup does actually have a number of health benefits. Onions are a great source of vitamin C, vitamin B6, iron, folate, and potassium. The part of this soup that makes it less healthy is the croutons and cheese on top, which you can certainly skip if you’d like.

Caramelizing onions is a low and slow process that isn’t difficult, but it is time-consuming. You want to cook your onions until they begin to brown, and then let them do their thing for a few hours, stirring frequently, until they are a deep chocolatey color. This recipe uses a more hands-off approach, but you can also caramelize onions on the stovetop. Follow this in-depth guide if you need a little extra help!

A dry white wine is any white wine that is not sweet. I like Sauvignon Blanc, Chardonnay, Riesling, or Pinot Grigio. You can also use white cooking wine, which can be found in the oil and vinegar aisle of the grocery store.

If your French onion soup tastes bitter, you most likely have burned the onions. The key to a great French onion soup is properly caramelized onions, which need to be cooked low and slow. Trust me, it’s worth the extra effort!

Serving Suggestions

This hearty soup is great on its own but you can, of course, amp things up with other dishes. Here are some faves:

• Mandarin Orange Salad
• Creamy Cucumber Salad
• Cucumber Tomato Salad
• Pesto Pasta Salad

One of the most satisfying moments is when your spoon delves in through that melty cheese into the rich broth and you pull out a spoonful of cheese, croutons and onion soup – delicious!

Storage Instructions

Store leftover French onion soup in an airtight container in the refrigerator for up to 3 days. I recommend leaving the croutons and cheese off until you’re ready to reheat and serve.

To reheat French onion soup, gently simmer in a saucepan set over medium heat until heated through, about 4-5 minutes. Alternatively, you can also place the soup in oven-safe containers and bake at 350°F for 10-20 minutes, stirring occasionally. Add a bit of water if the soup seems too thick.

Freezing Instructions

To freeze French onion soup, let it cool to room temperature, then portion and transfer to airtight containers or Ziplock bags. Freeze for up to 3 months. Allow the soup to thaw in the refrigerator before reheating and topping with croutons and cheese.

Substitutions

• To make this soup vegetarian, use vegetable broth instead of chicken broth.
• You can also use beef broth in place of the chicken broth for a darker, richer flavor.
• To make this soup gluten free, use gluten free croutons.
• Instead of cutting it into croutons, slice the baguette into 1-inch slices and place a slice on top of each bowl of soup. Add cheese and broil.
• If you’re not a fan of wine or don’t have any on hand, you can use an equal amount of broth in place of both the white wine and the sherry.

No broiler? No problem!

If you don’t have broiler-safe bowls, I recommend slicing the baguette into 1-inch slices and broiling those with cheese on top on a baking sheet. Alternatively, you can toast the bread and cheese in the toaster oven if you don’t have a broiler.

If you don’t have a broiler AND you don’t have a toaster oven, I recommend sprinkling a light layer of shredded cheese over top and letting the heat of the soup gently melt some of it.

Instructions

For the Soup

• Adjust oven rack to lower-middle position and preheat oven to 400°F. Spray a large Dutch oven with nonstick cooking spray.
• Place the olive oil and butter in the pot and add the garlic and onions. Sprinkle with 1 teaspoon kosher salt and stir well. Cook, covered, for 1 hour until the onions have reduced in volume and have softened. 2 tablespoons olive oil, 4 tablespoons unsalted butter, 1 clove garlic, 3 pounds yellow onions, 1 pound sweet yellow onions, 1¾ teaspoons kosher salt
• Remove the pot from the oven and stir, scraping the bottom and sides of the pan. Place the pot back into the oven and this time cover it with the lid left slightly ajar. Continue cooking the onions another 1 hour, and then give them another stir, scraping the bottom and sides of the pot. Return the pot to the oven, lid slightly ajar, and cook another 20-45 minutes or until the onions have completely softened and are golden brown.
• Carefully remove the pot from the oven and place it on the stove over medium-high heat.
• Cook the onions, stirring and scraping down the sides and bottom of the pot often, until the liquid evaporates and onions brown, 15-20 minutes. Reduce the heat to medium if the onions are browning too quickly. (Be careful NOT to burn the onions – the soup will be bitter.)
• Continue cooking and stirring until the bottom of the pot has a dark coating, then stir in ¼ cup chicken broth, scraping the pot bottom and sides to deglaze the pot. Cook until the water evaporates and a dark crust coats the bottom of the pot, about 6-8 minutes. Add another ¼ cup of broth to deglaze the pot once again. Repeat the process twice more or until the onions are very dark in color. 8 cups low sodium chicken broth
• Stir in the wine and the sherry and cook, stirring often, until the liquid has evaporated, about 3-5 minutes. ¼ cup dry white wine, ½ cup dry sherry
• Add the remaining broth, thyme, bay leaves, freshly ground black pepper, ¾ teaspoon salt, and stir well. Scrape the sides and bottom of the pot to release any bits of browned bits of food. Increase heat to high and bring to a low boil. 4 sprigs fresh thyme, 2 bay leaves, ½ teaspoon freshly ground black pepper
• Stir and reduce heat to low, cover, and simmer 30 minutes.
• Remove the thyme stems and bay leaves and season with salt and pepper, if needed.

For the Croutons

• Adjust oven rack to middle position and preheat oven to 350°F. Line a baking sheet with parchment paper.
• In a medium bowl, toss together the cubed bread, olive oil, melted butter, ¼ teaspoon salt, and ¼ teaspoon black pepper. Turn the bread cubes onto the prepared baking sheet and use a rubber spatula to scrape any remaining oil and seasonings over the croutons, tossing to mix. Bake until golden in color and crispy, 15-18 minutes. Transfer the croutons to the original bowl; set aside. 1 baguette, 2 tablespoons olive oil, 2 tablespoons salted butter, ¼ teaspoon kosher salt, ¼ teaspoon freshly ground black pepper

To Serve

• Increase oven temperature to 500°F (or set oven to “broil”) and line the baking sheet with aluminum foil. Spray 6 oven-safe bowls/crocks with nonstick cooking spray and place them on the lined, rimmed baking sheet.
• Divide the soup between the soup bowls (about 1½ cups each) and sprinkle with 2 tablespoons Gruyere. Top with croutons and sprinkle with the remaining Gruyere and then Parmesan. Broil for about 5-7 minutes, or until the cheeses are melted and gooey and the soup is bubbly around the edges. Let cool about 5 minutes before serving. 8 ounces shredded Gruyere or Swiss cheese, ½ cup shredded Parmesan cheese
• Garnish with chopped parsley or fresh thyme leaves, if desired. Chopped fresh parsley or thyme leaves

Equipment

• Dutch Oven
• Baking Sheet

This Essential Grocery List is an absolute life saver for my family on the busy weeks.

Essential Grocery List

It’s so helpful to have a basic grocery list to help me remember which foods to buy at the store. This food shopping list is my go-to!

It’s better to stock up on things like grains, seasonings and spices, baking essentials, oils, condiments, canned and frozen foods, etc. so I can just grab them when I need them. These things have a long shelf life , so I keep them in my kitchen for convenience.

However, I do have to go to the supermarket sometimes, and there’s a way to make that trip easy and hassle-free: I keep a grocery list! If I go in blindly, I’ll leave with things I don’t need, and nothing that actually helps me prepare a good meal.

In the list below, I’ve compiled everything I always have on my stock-up grocery list.

I’ve got you covered! I created an easy grocery list filled with all of the essentials. Plus there’s a free printable version that you can take with you to the grocery store. It has everything you need to stock your pantry, your freezer, and your refrigerator.

What to Buy at the Grocery Store
