Tips for the Best Soup

Low and slow is the trick. Caramelizing onions takes patience, but that golden color is worth every stir.
-
Cheese choices matter. Gruyere adds a nutty flavor, while Swiss is milder—both are delicious.
-
Don’t skip the sherry. It deepens the broth’s flavor, but a splash of white wine works in a pinch.
-
Want it creamier? Stir in a splash of heavy cream before serving for an extra-cozy twist.
-
Batch cook magic. This soup reheats beautifully, making it perfect for meal prep.
My Personal Story with This Soup
The first time I made this French Onion Noodle Soup, I wasn’t expecting much beyond a cozy dinner. But then… my kitchen smelled like a French café on a crisp autumn morning. My husband wandered in, eyes wide, asking if I had smuggled a Parisian chef into our home.
The kids? Shockingly, they didn’t complain about the onions (miracles do happen!). Instead, they slurped up every last noodle, cheese strings hanging from their mouths like happy little chandeliers. That was the moment I knew this recipe was going to stay in heavy rotation.
Now, whenever the weather dips below sweater-season temperatures, this soup makes an appearance at our table. It’s become more than a recipe—it’s a ritual.
What to Serve with French Onion Noodle Soup
This soup is hearty enough to stand alone, but pairing it with the right sides takes dinner to the next level:
-
Crusty bread or garlic toast (because dunking is half the fun).
-
A simple green salad with a tangy vinaigrette to cut through the richness.
-
Roasted veggies like carrots, Brussels sprouts, or green beans for balance.
-
A glass of red wine or apple cider to keep things cozy and seasonal.
Pro tip: If you’re entertaining, serve this soup in oven-safe bowls, melt cheese directly on top under the broiler, and watch your guests swoon.
How to Store and Reheat
Leftovers? Lucky you! This soup only gets better the next day.
-
Refrigerate: Store in an airtight container for up to 4 days.
-
Freeze: Cool completely, then freeze in portions for up to 3 months. Thaw overnight in the fridge before reheating.
-
Reheat: Warm on the stove over medium heat until steaming. If the noodles soak up too much broth, just add a splash of water or stock.
A quick tip: If you plan to freeze, cook the noodles separately and add them fresh when reheating. That way, they won’t get too soft.
FAQs About French Onion Noodle Soup
Can I make this vegetarian?
Yes! Use vegetable broth and skip the Worcestershire sauce, or use a vegetarian version.
What’s the best cheese for this soup?
Gruyère is classic, but Swiss, mozzarella, or even provolone will work in a pinch.
Can I substitute the sherry?
Absolutely. A splash of white wine, apple cider vinegar, or even extra broth works just fine.
How do I thicken the broth?
If you prefer a creamier consistency, stir in a cornstarch slurry (1 tbsp cornstarch + 2 tbsp water) during the simmer.
