Keto Crockpot Creamy White Lasagna Soup – Cozy, Low-Carb Comfort
If you love the creamy, cheesy comfort of white lasagna but want to keep it keto-friendly and hands-off, this soup hits the spot. It’s rich, satisfying, and loaded with flavor, yet surprisingly light on carbs. The slow cooker does most of the work, so you can go about your day while dinner makes itself.
Imagine a bowl of silky broth, tender chicken, ribbons of “noodles,” and a blend of Italian herbs—no oven, no fuss. One spoonful and you’ll know you’ve got a keeper.
Ingredients
Method
- Sauté your aromatics: In a skillet, warm olive oil or butter over medium heat. Add onion, celery, and mushrooms. Cook 5–7 minutes until softened. Stir in garlic and cook 30 seconds until fragrant. Transfer everything to the crockpot.
- Load the slow cooker: Add chicken thighs, chicken broth, Italian seasoning, dried basil, red pepper flakes, bay leaf, 1 teaspoon salt, and 1/2 teaspoon black pepper. Cover and cook on Low for 5–6 hours or on High for 2.5–3 hours, until the chicken is tender.
- Shred the chicken: Remove the chicken to a plate and shred with two forks. Discard the bay leaf. Return the chicken to the crockpot.
- Make it creamy: Whisk the softened cream cheese with the heavy cream in a bowl until mostly smooth. Stir the mixture into the crockpot. Add ricotta and half of the mozzarella. Stir until melted and silky.
- Finish with greens: Add chopped spinach and cook on High for 10–15 minutes until wilted. Taste and adjust salt and pepper. Add a small squeeze of lemon if you like brightness.
- Prepare your “noodles”: Choose one: Zucchini ribbons: Use a vegetable peeler to make wide ribbons. Salt lightly and let sit 10 minutes, then pat dry.
- Hearts of palm sheets: Slice into 1-inch strips; rinse and drain well.
- Spaghetti squash: Roast ahead (400°F, 35–45 minutes), then scrape into strands.
- Add the noodles wisely: Stir zucchini or hearts of palm into the hot soup and cook 3–5 minutes until just tender. For spaghetti squash, add right before serving to keep it from softening too much.
- Cheesy finish: Stir in the remaining mozzarella and the Parmesan. Let it melt. The soup should be creamy and slightly thick. If it’s too thick, add a splash of broth. If too thin, let it simmer uncovered on High for 10 minutes.
- Serve: Ladle into bowls, top with chopped parsley, extra Parmesan, and black pepper.

Storage Instructions
- Refrigerator: Store in airtight containers for 3–4 days. The flavors deepen by day two.
- Freezer: Freeze without the zucchini/hearts of palm for best texture.
Portion into freezer-safe containers and freeze up to 2 months. Thaw in the fridge overnight.
- Reheating: Warm gently on the stovetop over medium-low heat, stirring often. Add a splash of broth or cream if needed.
Add fresh “noodles” after reheating to avoid mushiness.
Why This is Good for You
- Low in carbs, high in satisfaction: Creamy fats and protein keep you full without spiking blood sugar.
- Protein-rich: Chicken provides lean protein for muscle maintenance and steady energy.
- Micronutrients in every bowl: Spinach, mushrooms, and zucchini bring fiber, potassium, folate, and antioxidants.
- Electrolyte-friendly: Broth and Parmesan offer sodium and minerals that can help support electrolyte balance on keto.
Pitfalls to Watch Out For
- Overcooking zucchini: It can turn watery and soft. Add near the end and cook just until tender.
- Cold cream cheese clumps: Soften it first and whisk with warm cream before adding to the crockpot.
- Too salty: Use low-sodium broth and season at the end after cheeses are added.
- Too thin or too thick: Adjust with more broth to thin, or simmer uncovered to reduce. Cheese thickens as it cools.
- Seizing dairy on high heat: Keep the heat moderate when adding dairy and avoid boiling.
Alternatives
- Protein swap: Use ground Italian sausage (brown first), rotisserie chicken, or turkey.
For pescatarian, try shredded rotisserie-style chicken substitute or add cooked shrimp at the end.
- Dairy adjustments: Replace ricotta with mascarpone for extra silkiness, or use cottage cheese (blended) for a lighter feel.
- Broth base: Bone broth adds more collagen and depth. Vegetable broth works if skipping chicken.
- Herb twist: Add fresh thyme or rosemary, or stir in pesto at the end for a basil-garlic lift.
- Heat level: Add more red pepper flakes or a pinch of white pepper for subtle warmth.
- Noodle options: Shirataki fettuccine can work if rinsed and sautéed first to remove odor and improve texture.
FAQ
Can I make this on the stovetop instead of a crockpot?
Yes. Simmer the chicken with aromatics and spices in a Dutch oven for 25–30 minutes until tender.
Shred, return to the pot, then add the cream mixture, cheeses, spinach, and “noodles.” Keep the heat low to prevent curdling.
How do I keep the soup from separating?
Soften the cream cheese and whisk it with warm cream before adding. Keep the heat below a boil once dairy goes in and stir gently as the cheeses melt.
What’s the best low-carb noodle for texture?
Hearts of palm strips hold their bite the best and don’t turn watery. Zucchini ribbons are convenient and light, but add them right at the end.
Spaghetti squash gives a cozy, slightly sweet taste and a nice twirl.
Can I make it ahead?
Absolutely. Cook the soup without the noodles, cool, and refrigerate up to 3 days. Reheat gently and add fresh zucchini, hearts of palm, or spaghetti squash just before serving.
Is this gluten-free?
Yes, as written it’s naturally gluten-free.
Always check labels on broth and cheeses to be safe.
How can I lower the calories while keeping it keto?
Use half the mozzarella and Parmesan, swap some heavy cream for unsweetened almond milk plus 2–3 ounces of cream cheese, and add extra mushrooms and spinach for volume.
Can I thicken it more without flour?
Yes. Let it simmer uncovered for a few minutes after adding cheese, or blend a cup of the soup and stir it back in. Extra Parmesan also adds body.
What can I use instead of ricotta?
Mascarpone is ultra-smooth and mild.
Blended cottage cheese works too and gives a slightly lighter texture.
How spicy is it?
It’s mild by default. Skip the red pepper flakes for no heat, or double them for a gentle kick.
Can I use frozen spinach?
Yes. Thaw, squeeze out excess moisture, and stir it in at the end.
It blends seamlessly and keeps the soup from getting watery.
