Light Chicken & Veggie Lasagna (Butternut Cream Sauce)

cozy, gluten-free comfort food from a tiny RV kitchen

Slice of light chicken and vegetable lasagna with creamy butternut squash sauce in a white baking dish, topped with melted cheese and herbs, served on a rustic wooden table.

If you love Italian comfort food like I do but can’t have the dairy, this is the recipe for you. It’s creamy, cozy, layered, and gives you all those classic lasagna vibes—without relying on heavy cream or traditional cheese sauces. The secret? A velvety butternut squash sauce that blends up smooth, rich, and honestly… kind of magical.

And let’s just say… this is one of those meals where your eyes might be a little bigger than your stomach. It’s so good, so comforting, and so satisfying that it’s very easy to go back for “just one more bite”… and then suddenly you’re sitting there wondering why you’re so full. Worth it though. Every creamy, cozy bite.

Equipment

  • Large skillet
  • Blender
  • 9×11 casserole dish
  • Pot for noodles
  • Cutting board + knife

Method
 

  1. Cook the Chicken: Add chicken, broth, salt, and garlic powder to Instant Pot. Cook on High Pressure for 10 minutes. Natural release 5 minutes, then shred finely.
  2. Cook the Butternut Squash: Heat skillet with 1 tbsp oil or ghee. Add squash and cook 5–7 minutes. Add 3–4 tbsp water or broth, cover, and steam until fork-soft.
  3. Cook the Vegetables: In the same skillet, cook onion, mushrooms, carrots, and zucchini for 8–10 minutes until very soft.
  4. Blend the Cream Sauce: Add cooked squash, vegetables, broth, coconut milk, garlic powder, nutmeg, and salt to a blender. Blend until completely smooth.
  5. Prepare Noodles: Cook noodles just until slightly underdone. Drain and set aside.
  6. Assemble Lasagna:
    In a 9×11 dish:
    1️⃣ thin layer sauce
    2️⃣ noodles
    3️⃣ chicken
    4️⃣ sauce
    5️⃣ cheese
    Repeat layers. Finish with sauce and cheese.
  7. Bake at 380°F for 20–25 minutes, loosely tented with foil to prevent over-browning.
    Remove foil and bake an additional 10–15 minutes until bubbly and lightly golden on top.
    Rest 10–15 minutes before slicing.

⭐ Golden Top Trick (Don’t Skip This)

Loosely tent the lasagna with foil for the first part of baking to prevent the top from getting too dark too quickly.

Remove the foil at the end so the cheese can melt and lightly brown without burning.

⭐ Tips

  • Blend sauce well so veggies disappear into creamy texture
  • Slightly undercook noodles to avoid mushy lasagna
  • Let rest before slicing for clean layers
  • Butternut naturally thickens sauce without heavy cream

Storage & Reheat

Storage:
Store in an airtight container in the fridge for up to 4 days.
For longer storage, freeze individual portions for up to 2 months.

Reheat:
Reheat in the microwave or warm in the oven at 350°F until heated through.
Add a small splash of broth if needed to keep the sauce creamy.
