All the ingredients and their quantities are in the recipe card below.
Some notes on a few of them:
- Carrots - we roast the carrots so they are tender and have a little sweetness.
- Zucchini - for some variety and to make a hidden veggie pasta sauce without tomatoes! Slice and roast for lots of flavor.
- Mascarpone cheese - this gives us a creamy carrot pasta sauce, adds a little protein and helps thicken the sauce too.
- Vegetable stock - used to make the sauce, you may like to see my low histamine veggie stock recipe!
🔪 How to Make Carrot Pasta Sauce
It's very easy to make this pasta with carrot sauce as a cozy family dinner with simple ingredients you may already have to hand!
All the instructions are in the recipe card below, but these step by step photos should help guide you.

Step 1: Roast the vegetables
Add your diced carrots and zucchini to a lined baking sheet. Drizzle with oil and sprinkle over the herbs and spice. Toss to coat the veggies and spread out in an even layer. Roast the carrots and zucchini until fork tender (image 1).

Step 2: Cook onion and garlic
Drizzle olive oil in your skillet or pan and cook the diced onion until softened. Add the minced garlic, and cook for a further minute or so (image 2).
Cook your pasta to package instructions, reserving half a cup of pasta water.

Step 3: Blend the pasta sauce
Spoon the roasted carrots and zucchini, and onion mix into your blender. Pour in the vegetable stock and add the mascarpone cheese. Season to taste. Blend the sauce until it is smooth. Adjust with more stock if too thick (image 3).

Step 4: Assemble the pasta
Tip your cooked pasta into the skillet, and pour in the carrot sauce. Stir together, adding spoonfuls of the reserved pasta water, as needed, to get the sauce consistency you like. Warm through, as required, and season to taste (image 4).
💭 Recipe Tips and Notes
- Dice the carrots and zucchini into rounds of a roughly similar size for an even cook time.
- Make sure the carrots are fork tender before blending, as that will give you a creamy sauce. Cook for a little longer, if needed.
- Don't forget to reserve the pasta water! The starch from it helps give us a smooth creamy sauce that coats the pasta.
