Chicken broth: I always use a rich, low-sodium broth so I can control the saltiness and it provides that comforting depth.
Eggs (for broth and spaetzle): Fresh eggs are best—especially since we’re tempering them into the hot broth for silky texture.
Fresh lemon juice: Use freshly squeezed, never bottled—it’s the key to a bright, zesty flavor.
Olive oil: Adds subtle richness to sautéed veggies without overpowering the soup.
Onion, garlic, celery, carrots: Classic aromatics that build savory depth and a wonderful veggie sweetness.
Fresh dill: A fresh garnish that gives a lovely herbaceous pop to the finished bowl.
All-purpose flour: The base for spaetzle—provides just the right texture when combined with eggs and milk.
Kosher salt & black pepper: Essential for balancing and enhancing all the flavors.
Ground nutmeg (for spaetzle): A subtle warming spice that beautifully complements the dough’s richness.
Milk (for spaetzle): Adds moisture and tenderness to the dumplings without making the batter too runny.

Tweak to Your Taste

I love that this Lemon Chicken & Spaetzle Soup Recipe is so adaptable. Once you know the core technique, you can customize the soup to your family’s tastes or what’s in your pantry. Don’t hesitate to make it your own by playing with herbs, adding veggies, or swapping milk for cream in the spaetzle.

Herb Twists: Sometimes I swap dill for fresh thyme or parsley depending on what I have—I find these herbs brighten the soup in different ways.
Vegetable Boost: I’ve occasionally tossed in mushrooms or green beans for added texture and earthiness—it works surprisingly well.
Spicy Touch: If you like a little heat, a pinch of red pepper flakes does wonders with the lemon flavor.
Dairy Variation: For a creamier spaetzle, swapping milk with half and half is a decadent option I try on weekends.

Step-by-Step: How I Make Lemon Chicken & Spaetzle Soup Recipe

Step 1: Sauté Your Base Veggies Gently

Start by warming up olive oil in a medium pot over medium heat. Toss in your finely chopped onion, garlic, celery, and carrots. Let them soften slowly for about 5 to 7 minutes until they’re fragrant and tender but not browned. This gentle sauté is key because it sweetens the veggies and avoids a harsh, burnt flavor that can happen if you rush this step.

Step 2: Heat the Broth and Combine

While your veggies are cooking, bring 6 cups of chicken broth to a gentle boil in a large pot. Once your vegetables are ready, add them right into the simmering broth. This layering of flavors really builds a hearty base for the soup.

Step 3: Make Your Spaetzle Batter

Mix flour, salt, and nutmeg in a large bowl. In another smaller bowl, whisk together eggs and milk until well blended. Gradually add this wet mixture into the dry ingredients, stirring until you get a smooth, thick batter—kind of like a sticky pancake batter. Set it aside, and don’t worry if it feels a bit lumpy; that happens often and is totally fine.

Step 4: Temper Eggs with Lemon for That Silky Finish

In a medium bowl, beat the 3 eggs with the fresh lemon juice until frothy. This mix is going to add brightness and silkiness to your soup, but you need to temper it carefully to avoid scrambled eggs in your broth. Slowly ladle a cup of the hot broth into the egg-lemon mixture while whisking constantly. This raises the temperature of the eggs gradually.

Step 5: Drop Spaetzle and Finish Soup

This is where the fun really begins. Use a spaetzle maker or drop spoonfuls of the batter into the simmering broth and veggies. Watch closely as they puff up and float to the surface—usually 2 to 3 minutes—that’s when they’re perfectly cooked. Next, stir in your tempered egg-lemon mixture gently, keeping the soup on low heat so it thickens slightly without boiling. Season with salt and pepper to bring all those bright, savory flavors together.

Step 6: Serve with Fresh Dill and Enjoy

Ladle your beautiful soup into bowls and sprinkle generously with fresh dill. That herbaceous pop is the perfect finishing touch that keeps the soup feeling fresh and vibrant. Now, grab a spoon and dig in—you’ve earned it!

Pro Tips for Making Lemon Chicken & Spaetzle Soup Recipe

Don’t Rush the Sauté: Taking your time to soften vegetables slowly unlocks their sweetness, making the broth richer and tastier.
Tempering is Key: Always whisk the hot broth into the egg mixture slowly to avoid curdled eggs and get that silky texture.
Watch the Spaetzle Closely: They cook fast—once they float, they’re done! Removing promptly keeps them tender, not mushy.
Season Gradually: Add salt and pepper at the end—you can always add more but you can’t take it out once it’s too salty.

Garnishes

I’m all about fresh dill on top—it adds that lovely herbal brightness. Sometimes I add a little lemon zest for extra zing or a small drizzle of good olive oil for a polished finish. A sprinkle of cracked black pepper on top never hurts either.

Side Dishes

This soup stands hearty on its own, but I like pairing it with crusty bread to soak up every last drop, or a simple green salad with a lemon vinaigrette to echo that fresh citrus note. For a heartier meal, roasted root vegetables are a lovely side too.

Creative Ways to Present

For dinner parties, I’ve served this soup in individual mini cocottes topped with a sprig of dill and a tiny wedge of lemon on the side. It’s super cozy and adds a bit of rustic charm. You can also sprinkle toasted almonds on top for a little crunch and visual interest.

Make Ahead and Storage

Storing Leftovers

I store leftover soup in an airtight container in the fridge for up to 3 days. The spaetzle does soak up broth over time, so I recommend reheating with a splash of water or broth to loosen it back up gently on the stovetop.

Freezing

This soup freezes okay, but if you want the best texture, freeze the broth and vegetables separately from the spaetzle. I usually make fresh spaetzle when thawing the soup, because the dumplings don’t freeze as well—they get a bit mushy.

Reheating

Reheat gently on low heat while stirring occasionally. Adding a little extra broth or water prevents the soup from getting too thick. Avoid boiling again after adding the eggs so you keep that silky smooth texture just right.

FAQs

Can I use store-bought spaetzle instead of making it fresh?

Absolutely! If you’re short on time, store-bought spaetzle works well. Just cook it separately according to package instructions and add it to the soup at the end so it doesn’t get mushy.
How do I make sure the eggs in the soup don’t scramble?

The secret is tempering: slowly whisking hot broth into your egg-lemon mixture before adding it back to the pot. Also, keep the heat low and avoid bringing the soup to a boil after adding the eggs.
Can I use chicken breast or thighs in this soup?

This recipe focuses on broth and spaetzle, but you can absolutely add cooked shredded chicken breast or thighs for extra protein. Add them near the end of cooking to warm through.
Is this recipe gluten-free?

The traditional spaetzle uses all-purpose flour, so this version isn’t gluten-free. For a gluten-free twist, you could experiment with gluten-free flour blends, but the texture will be different.

Final Thoughts

This Lemon Chicken & Spaetzle Soup Recipe holds a special place in my kitchen routines because it pairs simplicity with a little bit of flair. The fresh lemon flavor makes the broth feel lively, while the homemade spaetzle dumplings turn it into a meal that’s both comforting and exciting. I hope you enjoy making and sharing this soup as much as I do—it’s one of those recipes that feels like a warm hug in a bowl, perfect for any day you need a little extra love.
