Preheat your oven to 400 degrees F.
With a sharp knife, cut the vegetables and add them to a parchment lined baking sheet. Cut the tomatoes into quarters, the onion in half, the zucchini and carrots into chunks and chop just the top off of the 2 heads of garlic. Place all these veggies in a single layer on the baking sheet.
Drizzle oil over top of the veggies with salt and pepper. Massage the oil and salt and pepper into all of the veggies. Place the baking sheet in the oven and roast for about 30-40 minutes.
Towards the last 10 minutes of the veggies roasting, cook penne pasta until al dente and save 1 cup of pasta water. Set aside for now.
Once the veggies are done roasting, in a high speed blender add all of the roasted veggies, cottage cheese and 1 cup of vegetable broth. Blend this mixture on high until a smooth consistency appears and there are no lumps. Add more broth if you feel like the sauce is too thick and until it is your desired consistency.
Note: You will probably have more sauce than pasta. Only add what you need to your pasta and save the rest of the sauce for another time. I added about 1/2 of the sauce to my penne and saved the other 1/2 for another day. Stir the pasta and sauce together.
Garnish and serve the pasta with grated Parmesan cheese and fresh basil. Enjoy! 🙂
