Zupas Wisconsin Cauliflower Soup (Instant Pot Copycat)

Zupas Wisconsin Cauliflower Soup is one of those menu items people don’t stop thinking about — creamy, cheesy, comforting, and somehow lighter than it looks.

I know I couldn’t believe it was how good this soup was when me and my toddler first tried it! I immediately thought, I have to find a way to make this at home.

If you’ve searched for a way to recreate it at home, you’ve probably noticed two things: most copycat recipes are more complicated than expected, and many don’t actually taste that close to the original.

This Instant Pot version is designed to split the difference.

It stays true to the core flavors — cauliflower, cheddar, pepper jack, and cream cheese — while being honest about effort and flexible about shortcuts.

This is not a dump-and-go soup, but it is a realistic, repeatable way to get close to the Zupas experience at home without flour, roux, or restaurant equipment.

And, if you make enough, it freezes perfectly.

If you’re in the mood to cook and want something cozy that actually delivers, this recipe is worth making.

Tools You’ll Need to Make This Recipe

I received my Instant Pot for Christmas and it has quickly become my favorite tool in the kitchen! To make this soup I used:

• 6qt Instant Pot
• Cuisinart hand blender
• OXO box grater
• Meal prep essentials (cutting boards, garlic press, etc.)

What to Expect (Real Talk)

• Pressure cook time: 5 minutes
• Total time: ~30 minutes
• Effort level: Medium
• Best for: Cozy dinners, weekend cooking, dinner + next-day lunch

If you want a true blender-only soup, this isn’t it. If you want something that tastes like Zupas and doesn’t require standing over the stove for an hour, this version hits the sweet spot.

Why This Zupas’ Wisconsin Cauliflower Soup Instapot Recipe Works

Zupas’ Wisconsin Cauliflower Soup works because of ingredient balance, not technique overload.

This version mirrors that logic:

1. Cauliflower does the thickening

Instead of flour or starch, cauliflower is pressure-cooked until extremely tender and blended smooth. This creates body without heaviness and keeps the soup from tasting like a cheese sauce.

2. Cream cheese creates stability

Whipped cream cheese provides richness and helps emulsify the soup, making it more forgiving than recipes that rely on cream alone.

3. Cheddar + pepper jack = depth

Sharp cheddar delivers the classic flavor, while pepper jack adds subtle warmth. You don’t need spices or mustard to make this taste interesting.

4. Cheese is added after cooking

Adding cheese after pressure cooking prevents graininess and separation — the biggest reason many copycat soups miss the mark.

Shortcut-Friendly Ingredient Notes

This recipe is written to reduce friction, not add it.

Use these shortcuts guilt-free:

• Pre-cut cauliflower: Totally fine
• Pre-shredded cheese: Acceptable and faster
• Use the whole head of cauliflower: More payoff for the same work
• Skip bacon garnish: The soup stands on its own

Zupas’ Wisconsin Cauliflower Soup Copycat Ingredients

Base

• 3 tablespoons butter
• 1 small yellow onion, diced (I used half a large onion)
• 1 cup celery, diced (about 2-3 stalks)
• 3 cloves garlic, minced
• 1 medium head cauliflower, chopped (about 6–7 cups)

Liquids

• 3 cups low-sodium chicken or vegetable broth
• 1 cup whole milk or half-and-half

Cheese

• 1 tub (8 oz) whipped cream cheese
• 1½ cups sharp cheddar (pre-shredded or freshly grated)
• ½ cup pepper jack (pre-shredded or freshly grated)

Seasoning

• 1 teaspoon salt, plus more to taste
• ½ teaspoon black pepper

Optional garnish: shredded cheddar, cooked bacon

Instant Pot Instructions

1. Sauté the aromatics

Set the Instant Pot to Sauté (Normal). Melt the butter, then add onion and celery. Cook for 4–5 minutes until softened and translucent. Add garlic and cook for 30 seconds, just until fragrant.

2. Pressure cook

Add cauliflower and broth. Lock the lid, set the valve to Sealing, and pressure cook on High for 5 minutes. Quick release when finished.

3. Blend

Add milk and whipped cream cheese directly to the pot. Use an immersion blender to blend until completely smooth.

4. Add cheese gently

Switch the pot to Keep Warm or turn it Off. Add cheddar and pepper jack gradually, stirring until melted. Do not boil.

5. Taste and serve

Adjust salt and pepper as needed. Serve warm.

• Reheat gently on the stovetop or microwave at 50% power
