🔥 Step-by-Step Instructions for Making French Onion Gnocchi Soup

You don’t need to be a chef to pull this off. Just follow along.

1. Preheat Your Broiler

Set your oven’s broiler to high. You’ll need it later for that bubbling cheese top.

2. Caramelize the Onions

• In a large soup pot, melt the butter over medium-high heat.
• Add the onions, garlic, and brown sugar.
• Stir often for the first 10 minutes until the onions soften.
• Continue cooking another 15 minutes, letting them slowly deepen in color. This is where the magic begins.

3. Add the Thickener and Broth

• Reduce heat to low.
• Sprinkle in the flour and stir thoroughly to coat the onions.
• Cook for 5 minutes to remove the raw flour flavor.
• Pour in the broth gradually, stirring as you go.
• Add Worcestershire sauce, bay leaves, and thyme sprigs.
• Bring it to a gentle simmer.

4. Add the Gnocchi

• Drop the gnocchi straight into the simmering soup.
• Let them cook for 5 minutes, or until they float. That’s your sign they’re perfectly done.

5. Finish the Base

• Remove the bay leaves and thyme sprigs.
• Taste the broth and adjust with salt and pepper as needed.

6. Broil with Cheese

• Ladle the soup into oven-safe bowls.
• Sprinkle shredded Gruyère generously over each serving.
• Place the bowls on a baking sheet and broil for 3-5 minutes. Keep a close eye—you want golden bubbles, not burnt cheese.

7. Serve and Savor

• Garnish with fresh thyme.
• Serve immediately while the cheese is melty and irresistible.

🧐 Tips for Perfect French Onion Gnocchi Soup

You’re almost a pro at this, but a few pro tips can elevate your results:

• Caramelize low and slow—rushing equals burnt onions, not flavor.
• Stir regularly during caramelizing to avoid sticking.
• Use fresh thyme for better aroma and appearance.
• For texture lovers, pan-sear the gnocchi separately before adding.
• Want a richer broth? Add a splash of dry white wine with the flour.

🌿 Variations and Customizations

Whether you’re cooking for dietary needs or flavor adventures, here are ways to make this recipe truly yours:

• Vegetarian version: Swap beef broth for veggie broth; check your Worcestershire or sub it.
• Creamy twist: Stir in a splash of heavy cream before serving.
• Add protein: Toss in shredded rotisserie chicken or browned sausage.
• Low-carb: Use roasted cauliflower instead of gnocchi.
• Dairy-free: Opt for vegan butter and dairy-free cheese shreds.

Mix and match as needed. You’re in control.

🪣 Storage, Reheating & Make-Ahead Tips

Storage

• Keep in an airtight container in the fridge for up to 4 days.
• Cheese will harden, so stir gently when reheating.

Reheating

• Warm on the stovetop over medium heat.
• Add a splash of broth if it’s too thick.

Freezing

• The soup base (without cheese and gnocchi) freezes well.
• Gnocchi can get mushy when thawed, so add fresh after reheating.

Make-Ahead

• Make the onion broth a day early.
• Just reheat and add gnocchi and cheese before serving.
