How to Make Whole30 Lasagna Soup

1. Make the Homemade Italian Sausage

Place a large pot over medium-high heat. Add the ground beef along with black pepper, garlic powder, onion powder, dried basil, and oregano.
Cook, breaking the meat apart, until fully browned and cooked through. Transfer to a bowl and set aside.

2. Sauté the Aromatics

Return the pot to the stove and add olive oil. Reduce heat to medium.
Add chopped onion and cook for 4–5 minutes until soft and translucent. Stir in garlic and cook for 30–60 seconds until fragrant.

3. Build the Flavor Base

Return the cooked beef to the pot and stir in tomato paste. Cook for 2–3 minutes, allowing it to darken slightly—this deepens the flavor significantly.

4. Simmer the Soup

Pour in chicken broth and stir well. Add salt and crushed tomatoes.
Bring to a boil, then reduce heat and let simmer for 10 minutes to allow the flavors to meld beautifully.

5. Make the Cashew Cream

While the soup simmers, blend cashews and hot water in a high-speed blender until completely smooth and creamy.
Tip: Blend longer than you think—you want a silky texture with no graininess.

6. Add Creaminess

Pour the cashew cream into the soup and stir. Let it heat through for about 2 minutes, creating a luscious, creamy consistency.

7. Assemble and Serve

Place thinly sliced zucchini into serving bowls. Stir fresh basil into the soup, then ladle the hot soup over the zucchini.
Finish with a drizzle of olive oil and extra basil for a fresh, vibrant touch. Serve warm and enjoy.

Tips for Success

• Slice zucchini very thinly so it softens quickly in the hot soup
• Don’t skip browning the tomato paste—it adds depth and richness
• Blend cashew cream until ultra-smooth for the best texture
• Taste and adjust salt at the end for perfect seasoning
• Use high-quality canned tomatoes with no added sugar for Whole30 compliance

Equipment Needed

• Large pot (or Dutch oven)
• Medium mixing bowl
• High-speed blender (for smooth cashew cream)
• Knife or vegetable peeler (for zucchini noodles)

Recipe Variations

• Keto Version: Replace cashew cream with heavy cream or coconut milk (not Whole30 if using dairy)
• Spicy Twist: Add red pepper flakes or chili powder for a kick
• Vegetarian Option: Swap beef for plant-based crumbles and use vegetable broth
• Extra Veggie Boost: Add spinach, mushrooms, or bell peppers
• Chicken Version: Use ground chicken instead of beef for a lighter option

Serving Suggestions

• Serve with a simple green salad for a balanced meal
• Add a drizzle of olive oil and fresh basil for a restaurant-style finish
• Pair with roasted vegetables for extra heartiness
• For non-Whole30 eaters, a slice of crusty bread on the side is perfect

FAQs

Can I make this soup ahead of time?
