Ingredients for Keto Spinach Tomato Bisque

Gather these simple, fresh ingredients—most are probably in your kitchen already! Precision matters here, especially for keto, so measure carefully:

• 2 cups fresh spinach (packed—don’t skimp! This wilts down a lot.)
• 1 cup diced tomatoes (fresh or canned—just drain excess liquid)
• 1/2 cup heavy cream (full-fat for that luxurious texture)
• 2 tbsp butter (salted or unsalted, but adjust salt later if using salted)
• 1/2 onion, chopped (white or yellow, whatever’s on hand)
• 2 cloves garlic, minced (fresh—powder won’t give the same depth!)
• 2 cups vegetable broth (low-sodium if you’re watching salt)
• 1 tsp salt (start here—you can always add more)
• 1/2 tsp black pepper (freshly cracked if possible)
• 1/2 tsp dried basil (or 1 tsp fresh if you’re feeling fancy)

That’s it! No weird keto substitutes—just real, flavorful ingredients doing the heavy lifting.

How to Make Keto Spinach Tomato Bisque

Okay, let’s turn these simple ingredients into a creamy, dreamy bisque. Don’t rush the steps—each layer builds the flavor. Grab your favorite soup pot and let’s go!

Step 1: Sauté Aromatics

Melt the butter in your pot over medium heat. You want it just bubbling—no browning! Toss in the chopped onion and minced garlic, and let them sizzle gently for about 3-4 minutes until they’re soft and smell incredible. This is where the magic starts, so don’t skimp on time here.

Step 2: Cook Tomatoes and Spinach

Now, stir in those diced tomatoes. Let them cook down for 5 minutes—they’ll soften and get jammy, which deepens the flavor. Pour in the vegetable broth and bring it to a gentle simmer. Then, add the spinach in handfuls, stirring until it wilts into the broth like a leafy green hug. This takes about 2 minutes.

Step 3: Blend and Season

Time for the fun part! Grab your immersion blender (or carefully transfer to a stand blender) and puree everything until silky smooth. Now, stir in the heavy cream—watch how it swirls into that vibrant green like a sunset. Taste it! Add salt, pepper, and basil, adjusting until it’s just right for you. Remember: you can always add more, but you can’t take it out, so go slow.

That’s it—your bisque is ready to devour. Ladle it into bowls, maybe top with a extra drizzle of cream or a crack of pepper, and dive in. The whole process is so satisfying, you’ll swear you spent hours, but nope—just 30 minutes to bliss.

Tips for the Best Keto Spinach Tomato Bisque

Here’s how to take your bisque from good to unforgettable—little tricks I’ve picked up after making this dozens of times:

• Blend hot, serve hotter: The immersion blender works best when the soup is piping hot—it blends smoother and stays creamy.
• Cream last: Stir in the heavy cream after blending to prevent it from breaking or getting grainy.
• Greens hack: Swap half the spinach with kale for extra texture (just blend really well).
• Tomato tip: Roast canned tomatoes for 10 minutes first if you want a deeper, caramelized flavor.

And always, always taste before serving—adjusting salt and pepper is the secret handshake of great cooks.

Ingredient Substitutions

Out of something? No panic—this bisque is crazy flexible! Here are my tried-and-true swaps:

• Heavy cream: Use full-fat coconut milk for dairy-free (it adds a hint of sweetness that’s actually lovely).
• Fresh tomatoes: A 14-oz can of diced tomatoes works in a pinch—just drain half the liquid.
• Butter: Olive oil or ghee gives that same rich base.
• Spinach: Frozen works! Thaw and squeeze out excess water first.

The soul of this recipe stays intact—promise!

Serving Suggestions for Keto Spinach Tomato Bisque

This bisque is a star on its own, but oh—the things it loves to share a plate with! I love it with a slice of keto garlic bread (almond flour for the win) or a handful of crispy parmesan crisps for dipping. For heartier meals, pair it with grilled chicken or garlic butter shrimp—the creamy soup makes everything taste richer. And if you’re feeling fancy, top it with a dollop of sour cream and fresh basil. Trust me, no one will guess it’s keto!

Storage and Reheating

This bisque keeps like a dream! Store leftovers in an airtight container in the fridge for up to 3 days. When reheating, go low and slow on the stove—just warm it gently and stir often to keep that creamy texture perfect. If it thickens too much, splash in a little broth or water to loosen it up. Easy-peasy!

Frequently Asked Questions

Can I freeze this bisque?
Absolutely! Just let it cool completely, then freeze in airtight containers for up to 2 months. Thaw overnight in the fridge and reheat gently—stir in a splash of cream if it separates. Works like a charm!

Is this bisque dairy-free?
Almost! Swap the heavy cream for full-fat coconut milk (the canned kind) and use olive oil instead of butter. You’ll still get that velvety texture—just with a faint tropical twist. My dairy-free friends rave about it!

Why does my bisque taste bitter?
Ah, probably the spinach stems! Always tear off the thick stems before adding the leaves—they can add bitterness. Also, check your garlic isn’t burnt when sautéing (golden, not brown!). A pinch of sweetener can balance it out in a pinch.

Can I use frozen spinach?
You bet! Thaw it first, squeeze out all the water (seriously—get aggressive with that paper towel!), then add it when the recipe calls for fresh. Easy swap, same great flavor.
