What is Leftover Turkey Soup?

Leftover Turkey Soup is exactly what it sounds like—a smart, delicious way to use up extra turkey from your holiday feast, blended into a simple yet flavorful soup. Think of it as the sweater-weather version of a hug in a bowl. It starts with sautéed onions, celery, and carrots for that classic cozy flavor base, followed by chunks of turkey and Yukon gold potatoes that soak up all the savory goodness of a homemade (or store-bought—no judgment) stock.

But here’s what makes this soup actually filling: a quick roux thickens the broth just enough to feel rich without being too heavy. It’s the kind of meal that feels nostalgic but fresh—like a leftover remix that actually gets applause at the dinner table.

Reasons to Try Leftover Turkey Soup

First off, Leftover Turkey Soup is ridiculously easy. We’re talking 40 minutes from start to finish, with one pot and no complicated steps. That’s faster than your kids can argue about who’s unloading the dishwasher. Second, it stretches that pricey holiday bird into a brand new meal.

Waste not, want not, right? It also sneaks in a ton of veggies (hello, carrots, celery, onions, and potatoes), so you can feel good about feeding your family something nourishing post-pie. And if you’re juggling work, holiday chaos, and a fridge full of cranberry sauce, this soup will be your warm little sanity-saver. Plus, it’s super flexible—swap potatoes for rice, add peas, or even toss in some leftover green beans if you’re feeling wild.

Step by Step Instructions to Make Leftover Turkey Soup

This comforting Leftover Turkey Soup comes together easily with pantry staples and holiday leftovers. Follow this step by step guide to create a cozy, flavorful meal that’ll warm your belly and your soul.

Step 1: Sauté the Vegetables

Start by heating 2 tablespoons of canola oil in a large Dutch oven or heavy-bottomed soup pot over medium heat. Add in your diced carrots, celery, and onion (aka mirepoix—your soup’s flavor foundation). Stir occasionally for about 5 to 7 minutes, until the onions are translucent and everything smells sweet and savory.

Step 2: Add Garlic and Seasonings

Next, toss in your minced garlic, followed by salt, dried parsley, thyme, paprika, and a pinch of black pepper. Stir for one more minute to “wake up” the spices—this helps deepen the soup’s flavor without needing extra cooking time.

This step by step layering of aromatics is key to building a broth that tastes like it simmered all day—even if it hasn’t.

Step 3: Pour in the Stock and Scrape the Pot

Now, carefully pour in 3 cups of turkey stock (or chicken broth if that’s what you’ve got). As the liquid hits the pan, use a wooden spoon to gently scrape the bottom—those little browned bits from sautéing the veggies? That’s where the flavor lives.

Step 4: Add Potatoes and Simmer

Add the diced Yukon gold potatoes to the pot. Stir gently, then increase the heat to bring everything to a low boil. Once boiling, reduce the heat to medium-low, cover the pot, and let it simmer for about 10 minutes. The potatoes should be fork-tender—soft but not mushy.

Step 5: Make the Thickened Milk (Roux Method)

While the potatoes are cooking, it’s time to thicken things up. In a microwave-safe bowl or large measuring cup, melt ¼ cup salted butter. Stir in 3 tablespoons of all-purpose flour until it forms a smooth paste.

Slowly whisk in 1½ cups of milk, making sure there are no lumps hiding in the corners. Microwave the mixture in 45-second intervals, whisking after each round. After about 3 minutes total, the roux should be thick enough to coat a spoon.

Note: Want a gluten-free twist? Substitute the flour for a cornstarch slurry. Here’s how to make gluten-free thickened soups the easy way.

Step 6: Stir in the Turkey and Thickened Milk

Once the potatoes are tender, add your chopped leftover turkey to the pot. Stir gently to combine. Then pour in the thickened milk mixture, giving the soup a rich, velvety finish.

Simmer everything for 3–5 more minutes, just until it’s warmed through. Give it a taste and adjust seasonings if needed—maybe a little extra pepper, or a dash more salt.

Step 7: Serve and Enjoy

Ladle the hot soup into bowls and serve it as-is or with a hunk of crusty bread on the side. It’s a full meal in itself, but also plays well with a fresh green salad or buttery biscuit.

What to Serve with Leftover Turkey Soup

Honestly? This soup is filling enough to stand on its own, but if you’re looking to round it out, try pairing it with No Knead Artisan Bread or Homemade Breadsticks. Craving some greens? Air Fryer Broccoli or Roasted Green Beans will balance out all that cozy richness. For a Southern twist, a buttery Crescent Roll is basically soup’s best friend. And if your fridge is still playing post-Thanksgiving Tetris, toss in those leftover green beans or a scoop of stuffing on the side for a little bonus flavor.

Key Tips for Making Leftover Turkey Soup

1. Use what you’ve got. No turkey stock? Chicken broth works great. No potatoes? Add rice or pasta.
2. Cut veggies small. This helps everything cook quickly and evenly, especially if you’re short on time.
3. Make the roux thick. You want it to coat a spoon without running off. It’ll help give the soup that comforting, creamy texture.
4. Don’t skip seasoning. Herbs and spices are the heart of the flavor here. Taste as you go!
5. Make ahead if you can. This soup tastes even better the next day, after everything gets cozy in the fridge overnight.

Storage and Reheating Tips for Leftover Turkey Soup

Store leftover turkey soup in an airtight container in the fridge for up to 3 days. Let it cool a bit before refrigerating (because hot soup + fridge = not great). Reheat it on the stove over low heat or in the microwave, stirring every minute or so to prevent that weird microwave lava situation. Freezing? Totally doable—but skip the potatoes. They can get weirdly grainy when frozen and reheated. Instead, swap in rice or freeze the broth + turkey + veggies, then add potatoes fresh when you reheat.

FAQs

Can I use chicken instead of turkey?
Absolutely! Leftover rotisserie chicken is a great stand-in.

Can I make it dairy-free?
Yes. Use olive oil instead of butter and swap milk for a plant-based version like oat or almond.

What’s the best way to make this gluten-free?
Instead of flour for the roux, mix cornstarch with cold milk and stir it into the hot soup at the end to thicken.

Can I add noodles instead of potatoes?
You bet. Use 1 to 1½ cups of uncooked pasta and add it when you’d normally add the potatoes.

How long does this soup keep?
It’s best within 3 days in the fridge but can be frozen for up to 2 months (just leave the potatoes out).
