The bacon starts with a soft sizzle, then the edges curl and turn crisp while the Dutch oven fills with a smoky, savory smell. That first layer of flavor sets up Creamy Potato Leek Soup with Crispy Bacon, but the soup isn’t relying on bacon alone. Tender leeks bring a mild sweetness, and Yukon Gold potatoes give the broth enough body to feel like a full meal.
I like the balance here: the soup is smooth and mellow, with a little cream to round it out and crisp bacon on top to keep each spoonful from feeling one-note. Cooking the leeks gently matters; they should soften into the base, not brown and take over. The finished bowl is rich without being heavy, with a clean leek flavor beneath the bacon’s salty crunch.
Kitchen Note
Leeks can hide grit between their layers, and it’s easy to miss until it’s in the soup. Rinse the sliced leeks well and let them drain before they go into the butter; grit won’t disappear when the soup is blended smooth.
Save this creamy potato leek soup with crispy bacon for its velvety potato base and crisp, savory finish.
Why Yukon Golds Make This Soup Creamy Before the Cream Goes In
Potatoes decide whether a blended soup feels velvety or pasty, and Yukon Golds are a dependable middle ground. They have enough starch to give the broth body, while their naturally creamy texture blends into a smooth base. That means the heavy cream is there to add richness, not to rescue a thin soup.
Very starchy potatoes can become gluey when they’re worked hard in a blender, while waxier potatoes may not give the broth the same soft, full texture. Yukon Golds suit this method particularly well because they simmer until tender and blend evenly with the leeks and broth. Keep the pieces consistent when you cut them so they reach that tender stage at about the same time. The potatoes do the quiet structural work that makes each bowl feel substantial.
What the Leeks, Potatoes, and Cream Each Bring to the Pot
- Thick-cut bacon — Its wider pieces stay substantial as they crisp, giving the soup a crunchy finish rather than a scattering of tiny bits. A standard grocery-store package works well; even-sized pieces help them cook at a similar pace.
- Leeks — The white and light green parts turn soft and mild, making a gentler base than a sharper onion flavor. Choose firm leeks without slimy spots; the usable sections are already specified, so save the dark green tops for another use.
- Yukon Gold potatoes — Their creamy texture helps give the blended soup its body. Peeling keeps the finished soup smooth, and Yukon Golds are the best fit for this texture; a different potato won’t produce quite the same result.
- Low-sodium chicken broth — Broth is the soup’s main cooking liquid, and the low-sodium kind leaves room to season without the bacon and salt making the bowl too assertive. If you only have regular-sodium broth, use less kosher salt and taste the soup before serving.
- Unsalted butter — Butter carries the leek, garlic, and thyme flavors as they soften in the pot. If salted butter is what you have, reduce the added kosher salt rather than seasoning at the same level.
- Garlic and dried thyme — Garlic gives the base a savory note, while dried thyme adds a quiet herbal background. There’s no need for a premium brand of dried thyme; the minced garlic should be fresh for its clean, warm aroma.
- Heavy cream — Cream gives the finished soup a rounder, silkier feel. It’s worth using heavy cream for that richness; leaving it out makes a lighter, less creamy bowl rather than an exact substitute.
- Bay leaf, kosher salt, and black pepper — The bay leaf adds a subtle savory aroma during the simmer, and the salt and pepper season the potatoes and broth from the start. Remove the bay leaf before blending so no tough piece ends up in a bowl.
From Crisp Bacon to a Smooth, Cream-Finished Soup
Render the bacon until the edges crisp
Put the thick-cut bacon pieces in a 6-quart Dutch oven over medium heat. Cook for 8 to 10 minutes, stirring occasionally, until the pieces are crisp rather than merely browned. Transfer them to a paper towel-lined plate. Pour off and discard the rendered fat, then wipe out the pot so the soup base doesn’t turn greasy.
Soften the leeks in butter
Melt the butter in the same Dutch oven over medium heat, then add the rinsed leeks. Cook for 7 to 8 minutes, stirring now and then, until they’re softened; they should look relaxed and tender, not browned at the edges. Stir in the minced garlic and dried thyme. Give them 30 seconds to turn fragrant, then move on before the garlic darkens.
Simmer until the potatoes are very tender
Add the cubed potatoes, chicken broth, kosher salt, black pepper, and bay leaf. Bring the pot to a boil, then reduce the heat and simmer uncovered for 15 to 20 minutes. The potatoes should be very tender and yield easily when pressed with a fork. If they’re still firm in the center, give them more time before blending.
Blend first, then warm the cream gently
Remove and discard the bay leaf, then take the pot off the heat. Blend with an immersion blender until the soup is smooth, keeping the blender head submerged to limit splashing. Stir in the heavy cream and return the pot to low heat for 2 to 3 minutes. Don’t let the soup boil; ladle it into bowls and finish each one with the crispy bacon.
How to Change the Finish Without Losing the Leek Base
A dairy-free bowl with potato body
Leave out the butter, heavy cream, and bacon. Soften the leeks in a splash of the measured broth, then add the remaining broth with the potatoes and seasonings. The soup won’t have the same silky richness, but the blended potatoes still give it a smooth, filling texture.
A cream-free, broth-forward version
Keep the butter and bacon, but leave out the heavy cream if you want a less rich bowl. The potatoes still bring body after blending, while the broth and leek flavor come through more clearly. It won’t have the same rounded finish as the creamy version.
A more leek-forward soup without thyme
Leave out the dried thyme and keep the rest of the ingredients and method the same. The soup will have a simpler, more direct leek-and-garlic flavor, with less herbal warmth in the background.
Storage and Reheating
- Refrigerator: Refrigerate in a covered container for 3 to 4 days. The potatoes will make the soup thicker as it sits.
- Freezer: The finished soup doesn’t freeze especially well; potatoes can turn grainy and the cream may separate after thawing.
- Reheating: Warm it gently over low heat, stirring occasionally, and don’t let it boil. Bacon topping softens in stored soup, so keep it separate if you want it crisp.
