Garlic-Butter Loaded Baked Potato Soup Without Flour
Garlic-butter loaded baked potato soup gets its thick, spoon-coating body from warm riced russets rather than a heavy flour paste. I microwave the potatoes while the bacon renders in the Dutch oven, then finish every bowl with foaming, smoky garlic butter.

Why Ricing Potatoes Beats Adding Flour
- Parallel 15- to 17-minute prep: Cooking the pierced russet potatoes in the microwave while the thick-cut bacon crisps in the Dutch oven skips an hour of oven baking and puts bowls on the table in 40 minutes.
- Blended onion and dairy base: Simmering finely chopped yellow onion with grated garlic cloves, whole milk, and low-sodium chicken broth before puréeing builds a savory liquid foundation that never mutes the melted cheddar.
- Intact potato starch: Pressing warm potato halves cut-side down with a potato ricer traps the tough skins inside the hopper while keeping the starch cells whole, so a lifted spoonful mounds softly before settling back into the pot.
- Bloomed paprika butter swirl: Heating unsalted butter with grated garlic and smoked paprika for 45 to 60 seconds right before serving puts toasted aroma on the surface where you taste it first.
Key Ingredients for Thick Baked Potato Soup
- Russet potatoes: High-starch, low-moisture russets break down into dry, fluffy strands that thicken the dairy naturally. Waxy red or yellow potatoes hold too much water and leave the broth thin.
- Extra-sharp yellow cheddar cheese: Grate chilled block cheese yourself using the fine holes on your grater. Bagged shreds carry powdery coatings that clump and feel gritty in a flourless base.
- Full-fat sour cream: Let the ¾ cup meant for the pot sit on the counter while you prep so it blends smoothly into the warm liquid, and keep the remaining ⅓ cup cold in the fridge for topping.
How to Make Garlic-Butter Loaded Baked Potato Soup
1. Cook the russets in the microwave. Pierce the scrubbed russet potatoes all over with a fork so steam can vent safely, arrange them in a single layer on a microwave-safe plate, and run on high for 15 to 17 minutes, flipping them halfway through. They are ready when the tip of a paring knife slides into the center with zero resistance; let them rest on the counter for 5 minutes until cool enough to hold.
2. Render the thick-cut bacon. While the microwave runs, add the ½-inch bacon pieces to a 5- to 6-quart Dutch oven over medium heat and stir often for 8 to 10 minutes until deep rust-gold and crisp. Transfer the bacon to a paper towel-lined plate with a slotted spoon, and pour off all but 2 tablespoons of the hot drippings.
3. Soften the aromatics and simmer the liquid. Stir the finely chopped yellow onion into the reserved bacon drippings over medium heat for 6 to 7 minutes until translucent and tender without browning. Add half of the grated garlic cloves and cook for 1 minute until fragrant, then pour in the whole milk, low-sodium chicken broth, Diamond Crystal kosher salt, and black pepper. Bring the pot to a gentle bubble over medium-high heat, lower the burner to medium-low, and simmer uncovered for 6 to 8 minutes until the onion pieces are completely soft.
4. Purée the liquid and press the potatoes. Pull the Dutch oven off the heat first so hot dairy does not splatter, then blend the onion and milk mixture with an immersion blender for 45 to 60 seconds until smooth. Cut the warm potatoes in half crosswise, set each piece cut-side down inside a potato ricer, and press the fluffy flesh straight into the pot, discarding the flattened peels left inside the hopper.
5. Melt the cheddar and sour cream over low heat. Return the pot to low heat and whisk the riced potatoes into the hot liquid until thick. Add the 1 cup of shredded cheddar and room-temperature sour cream in small handfuls, whisking nonstop for 2 to 3 minutes until heated through to 165°F (74°C) without boiling. When my burner creeps past low during this final warm-up, the dairy splits into tiny oil beads around the rim of the Dutch oven and the cheddar turns stringy on the whisk.
6. Bloom the garlic butter and garnish the bowls. Combine the unsalted butter, remaining grated garlic cloves, and smoked paprika in a small microwave-safe bowl and heat on high for 45 to 60 seconds until foaming and the garlic smells sweet and toasted. Stir half of the crispy bacon into the pot, ladle into 6 warm bowls, and divide the remaining cheddar, sour cream, bacon, sliced fresh chives, and warm smoky garlic butter on top.
Making Baked Potato Soup Without a Ricer
If you do not keep a ricer in a kitchen drawer, a wire potato masher handles step four with one quick adjustment. Halve the warm cooked russets, spoon the soft centers out of their skins into a mixing bowl, and work them thoroughly with the masher before whisking them into the puréed onion and milk base. Never use your immersion blender after the potatoes enter the pot, because spinning blades tear open swollen starch cells and turn the texture gluey; expect a slightly rustic spoonful with tiny potato flecks instead of a uniform purée.
What to Serve with Loaded Baked Potato Soup
Holding the ladled bowls on the counter for two minutes before calling everyone to the table is my favorite move, since that brief pause lets the cold sour cream and shredded cheddar melt halfway into the hot paprika butter without sinking to the bottom. Because a 1 ½-cup serving brings plenty of starch and rich dairy on its own, skip heavy bread sides and pair your bowl with crisp roasted lemon garlic asparagus for bright acidity.
Storing and Reheating Leftover Potato Soup
- Fridge storage: Cool leftover soup completely, transfer it to an airtight container, and refrigerate for 3 to 4 days. Pack extra bacon and sliced chives in separate small containers so the bacon stays crisp.
- Gentle reheating: Warm leftovers in a saucepan over low heat, stirring frequently and adding a splash of whole milk or chicken broth to loosen the thickened potato base until it reaches 165°F (74°C) without boiling.
- Skip the freezer: Dairy-rich soups thickened with russet potatoes, sour cream, and melted cheddar separate and turn grainy once thawed.
Common Questions About Garlic-Butter Potato Soup
Can I bake the russet potatoes in the oven instead of the microwave?
Yes, you can bake the pierced russet potatoes directly on an oven rack at 400°F for 50 to 60 minutes until a paring knife slides cleanly into the center. Oven-baked flesh is slightly drier than microwaved potatoes, so whisk in an extra splash of milk or broth if the base feels too dense.
Why did my cheddar potato soup turn grainy?
Grainy texture happens when pre-shredded bagged cheese is used or when the soup simmers after the dairy goes in. Grating block cheddar yourself and keeping the burner on low below a boil ensures a smooth, glossy melt.
Can I prep the ingredients ahead of time?
You can chop the yellow onion and crisp the thick-cut bacon up to 2 days ahead, storing the cooked bacon and its 2 tablespoons of drippings in covered containers in the refrigerator. Wait to microwave and rice the russets until you are ready to cook so their starch stays fluffy.
When you want a cool, tangy bite after a rich bowl, pull a tray of lemon raspberry frozen yogurt bark from the freezer, or try my cozy pumpkin chowder on your next chilly soup night.
Swirling that warm, brick-red paprika butter through the cool sour cream right at the table makes a 40-minute weeknight dinner feel like a steakhouse treat. Save this recipe now so you have the exact microwave-and-ricer routine ready the next time a soup craving hits.

- Yield9 cups (serves 6) 1x
Ingredients
Soup Base
- 3 pounds (1.35 kg) russet potatoes (about 4 large), scrubbed
- 8 ounces (225 g) thick-cut bacon (about 7 slices), cut into ½-inch (1.3-cm) pieces, divided
- 1 large yellow onion (10 ounces / 285 g), finely chopped
- 2 large garlic cloves (10 g), finely grated
- 3 cups (710 mL) whole milk
- 1 cup (240 mL) low-sodium chicken broth
- 1 ½ teaspoons (4.5 g) Diamond Crystal kosher salt (or ¾ teaspoon table salt), plus more to taste
- ½ teaspoon (1 g) freshly ground black pepper
- 1 cup (4 ounces / 115 g) freshly shredded extra-sharp yellow cheddar cheese
- ¾ cup (180 g) full-fat sour cream, warmed to room temperature
Garlic-Butter Swirl and Toppings
- 3 tablespoons (42 g) unsalted butter
- 2 large garlic cloves (10 g), finely grated
- ¼ teaspoon (0.5 g) smoked paprika
- ½ cup (2 ounces / 55 g) freshly shredded extra-sharp yellow cheddar cheese
- ⅓ cup (80 g) full-fat sour cream
- ⅓ cup (16 g) finely sliced fresh chives
Instructions
- Microwave the potatoes: Prick the scrubbed potatoes all over with a fork so steam can escape. Place them in a single layer on a microwave-safe plate and microwave on high, flipping them halfway through, for 15 to 17 minutes until the centers yield easily to the tip of a paring knife. Let stand on the counter for 5 minutes until cool enough to handle.
- Crisp the bacon: While the potatoes cook, place the chopped bacon in a 5- to 6-quart (5- to 5.5-L) Dutch oven over medium heat. Cook, stirring often, for 8 to 10 minutes until deep golden brown and crisp. Use a slotted spoon to transfer the bacon to a paper towel-lined plate, and pour off all but 2 tablespoons (30 mL) of the rendered drippings from the pot.
- Cook the aromatics and simmer the base: Add the chopped onion to the hot bacon drippings and cook over medium heat, stirring occasionally, for 6 to 7 minutes until translucent and tender without browning. Stir in the 2 grated garlic cloves for the soup base and cook for 1 minute until fragrant. Pour in the whole milk, chicken broth, kosher salt, and black pepper. Bring to a gentle bubble over medium-high heat, then reduce the heat to medium-low and simmer uncovered for 6 to 8 minutes until the onion is completely soft.
- Purée the liquid and rice the potatoes: Remove the pot from the heat and blend the onion-milk mixture with an immersion blender for 45 to 60 seconds until completely smooth. Cut the warm potatoes in half crosswise, place each piece cut-side down into a potato ricer, and press the fluffy flesh directly into the pot, discarding the flattened skins trapped inside the hopper.
- Melt in the cheddar and sour cream: Return the pot to low heat and whisk the riced potatoes into the hot liquid until smooth and thick. Add the 1 cup (115 g) shredded cheddar and ¾ cup (180 g) room-temperature sour cream in small batches, whisking constantly for 2 to 3 minutes until melted, velvety, and heated through to 165°F (74°C) without letting the soup boil. Taste and adjust with additional salt if needed.
- Make the garlic-butter swirl and serve: Combine the unsalted butter, remaining 2 grated garlic cloves, and smoked paprika in a small microwave-safe bowl; microwave on high for 45 to 60 seconds until foaming and the garlic smells sweet and toasted. Stir half of the crispy bacon into the soup and ladle into 6 warm bowls. Divide the remaining ½ cup (55 g) cheddar, ⅓ cup (80 g) sour cream, remaining crispy bacon, sliced chives, and warm smoky garlic butter among the 6 bowls.
Notes
- Why it works: Pressing microwaved russet halves cut-side down through a potato ricer separates the skins automatically while keeping the starch granules intact, giving the soup a plush, velvety body without ever turning gummy—and without needing a flour roux that mutes the potato flavor.
- Shred cheese from a block: Pre-shredded bagged cheddar is coated in anti-caking starches that can make a non-roux soup turn grainy when melted; grate a cold block of extra-sharp cheddar on the small holes of a box grater so it melts smoothly into the warm base in seconds.
- No-ricer option: If you do not own a potato ricer, scoop the warm potato flesh into a bowl and mash thoroughly with a standard hand masher before whisking it into the blended onion-milk base; avoid blending the potatoes themselves with the immersion blender, which ruptures the starch and makes the texture pasty.
