How To Make Keto Lasagna Soup
Let’s dive into the cooking process—just a few straightforward steps to build layers of flavor and a creamy, comforting finish. You’ll brown your meats, sauté aromatics, simmer the zucchini in spiced broth, and finish with a dreamy blend of cheeses and cream.
1. Heat olive oil in a large pot over medium heat. Add ground beef and Italian sausage, breaking the meat into crumbles with a spoon. Cook until the meat is well browned and no pink remains, about 6–7 minutes.
2. Add diced onion and minced garlic to the pot. Sauté for 3–4 minutes, stirring frequently, until the onion is translucent and the garlic is fragrant.
3. Stir in zucchini, dried basil, Italian seasoning, and red pepper flakes. Cook for 2 minutes, tossing the zucchini so it’s evenly coated in the herbs and spice.
4. Pour in chicken broth and sugar-free marinara sauce. Increase heat to bring the mixture to a gentle boil, then reduce to a simmer. Let it simmer uncovered for 10 minutes to marry the flavors.
5. Add cream cheese and heavy cream, stirring continuously until the cream cheese fully melts and the soup becomes smooth and creamy.
6. Stir in shredded mozzarella and grated Parmesan. Continue cooking for 2–3 minutes more, stirring gently until all the cheese is melted and the soup has a luscious, cheesy consistency.
7. Season with salt and black pepper to taste. Ladle the soup into bowls and garnish each serving with chopped fresh parsley.
Serving Suggestions
This comforting soup is delicious on its own or paired with light sides to round out your meal. Here are four ideas to elevate the experience:
- Serve with a crisp Caesar salad topped with shaved Parmesan and a tangy dressing for a refreshing contrast.
- Offer warm garlic kale crisps or roasted broccoli on the side for extra veggie goodness.
- Pair with slices of toasted keto bread or cheesy almond-flour biscuits to soak up every drop.
- Garnish with a dollop of sour cream or plain Greek yogurt and an extra sprinkle of red pepper flakes for creaminess and heat.
Tips For Perfect Keto Lasagna Soup
Making this soup is a breeze, but these friendly pointers will take your bowl from great to unforgettable:
- Use zucchini as a low-carb substitute for traditional lasagna noodles.
- Adjust red pepper flakes for more or less heat according to preference.
- Store leftovers in an airtight container in the refrigerator for up to four days.
- Freeze individual portions for up to two months and thaw in the refrigerator before reheating.
How To Store It
After enjoying a steaming bowl, you’ll want to keep those flavors fresh for days to come. Proper storage not only maintains the creamy texture but also ensures every spoonful tastes as good as day one.
- Refrigerate in airtight containers: Allow the soup to cool slightly, then transfer to sealed containers. Store in the fridge for up to four days.
- Freeze for long-term storage: Portion the cooled soup into freezer-safe containers or bags, seal, and freeze for up to two months. Thaw overnight in the refrigerator before reheating.
Frequently Asked Questions
Here are answers to all the common questions about Keto Lasagna Soup:
- Q: How long does it take to prepare this Keto Lasagna Soup?
A: From start to finish, this recipe takes about 30 to 35 minutes. You’ll spend 5 to 7 minutes browning the ground beef and Italian sausage, 3 to 4 minutes sautéing the onion and garlic, 2 minutes cooking the zucchini with the spices, 10 minutes simmering after adding broth and marinara, and another 5 minutes melting in the cheeses and cream.
- Q: How should I store and reheat leftovers?
A: Store any leftover soup in an airtight container in the refrigerator for up to four days. To reheat, transfer to a pot over medium-low heat, stirring occasionally and adding a splash of chicken broth or heavy cream if the soup has thickened. You can also microwave individual portions in a microwave-safe dish, stirring halfway through to ensure even heating. For longer storage, freeze single servings in freezer-safe containers for up to two months, then thaw overnight in the refrigerator before reheating.
- Q: Can I substitute the zucchini with another low-carb vegetable?
A: Yes, you can swap zucchini for other low-carb veggies such as diced eggplant, spaghetti squash strands, or yellow squash. Keep the cooking time similar, though eggplant may release more moisture and require a few extra minutes to soften. If you choose spaghetti squash, roast or microwave it separately first and stir it in at the end so it doesn’t become too mushy.
- Q: How can I adjust the spiciness of this soup?
A: To increase heat, add a pinch of cayenne pepper, chopped fresh jalapeño, or an extra 1/4 teaspoon of red pepper flakes when you add the Italian seasoning. To tone down the spice, reduce the red pepper flakes or omit them entirely. You can also stir in a spoonful of sour cream or plain Greek yogurt just before serving to cool the soup and balance the flavors.
- Q: Is it possible to make this recipe dairy-free or lower in calories?
A: For a dairy-free version, substitute the cream cheese with a dairy-free cream cheese alternative, replace heavy cream with coconut cream, and use a plant-based shredded cheese. Note that these swaps may alter the flavor profile and slightly change the soup’s consistency. To lower calories while keeping it keto-friendly, reduce the cream cheese to 2 ounces and use half-and-half instead of heavy cream, then adjust seasoning to taste.
- Q: How can I thicken the soup if it’s too thin?
A: If the soup is thinner than you like, simmer it uncovered for a few extra minutes to reduce excess liquid. You can also stir in an additional ounce or two of cream cheese or shredded mozzarella to achieve a richer, thicker texture. For a low-carb thickening alternative, sprinkle in a small pinch of xanthan gum while whisking vigorously to prevent clumping.
- Q: Can I make this soup vegetarian or vegan?
A: To make a vegetarian version, omit the ground beef and sausage and use plant-based sausage crumbles or cooked lentils, then swap chicken broth for vegetable broth. For a vegan adaptation, use vegan meat crumbles, vegetable broth, dairy-free cream cheese and heavy cream alternatives, and vegan mozzarella and Parmesan substitutes. Adjust seasonings as needed, since plant-based proteins can absorb more spice.
