Can I use frozen or homemade gnocchi instead of shelf-stable?

Yes, both work perfectly. Adjust cooking time frozen gnocchi may need 1–2 extra minutes.

Do I really need 4 pounds of onions?

Yes! Onions shrink dramatically when caramelized, creating a rich, sweet base.

What is a good vegetarian substitute for beef broth?

A mix of mushroom broth and vegetable broth adds similar depth.

My onions are burning before they caramelize. What do I do?

Lower the heat and add a splash of broth or water to deglaze.

Can I use a slow cooker for this recipe?

Yes, cook onions on low for 4–5 hours, then add the rest and simmer another hour.

I don't have oven-safe soup crocks. How can I broil the cheese?

Place soup in oven-safe bowls on a baking sheet under the broiler.

Can I freeze this soup?

Freeze the base without cheese or gnocchi. Add them fresh when reheating.

How long does it take to properly caramelize onions?

Around 25–30 minutes over medium-low heat for perfect color and flavor.

What is the best type of cheese to use for the topping?

Gruyere cheese gives the best melt and flavor, but Swiss or Parmesan also work.

Can I make the broth ahead of time?

Yes, you can prepare the base 1–2 days in advance and add gnocchi before serving.

Instructions

In a large pot or Dutch oven, heat butter and olive oil over medium-low heat. Add onions and cook slowly, stirring occasionally.
After 20 minutes, add brown sugar and continue cooking until onions are deep golden and caramelized.
Stir in garlic, tomato paste, and flour. Cook for 1 minute to form a light roux.
Pour in red wine or sherry, scraping the bottom of the pot to deglaze.
Add broth, thyme, parsley, bay leaf, and Worcestershire sauce. Simmer gently for 15 minutes.
Add gnocchi directly into the pot and cook until they float and become tender.
Ladle soup into oven-safe bowls, top with cheese, and broil until bubbling and golden brown.
Serve hot and enjoy with crusty bread or a side salad.

Notes

For a vegetarian version, use vegetable broth and omit Worcestershire sauce. To make it vegan, substitute butter and cheese with plant-based options. Use gluten-free gnocchi and cornstarch instead of flour for a gluten-free variation. Caramelize onions slowly for the richest flavor.
