Freezer: If you want to keep it longer, freeze the sauce in a freezer-safe container for up to 2 months. Thaw overnight in the fridge before reheating.

Creamy Roast Garlic and Lemon Pasta Sauce Recipe FAQs
What should I look for when selecting garlic?
Choosing the right garlic is essential for maximum flavor! Look for heads that are firm and tightly closed, without any dark spots or signs of sprouting. Fresh garlic will have a strong aroma and will feel heavy for its size. If you spot any dark spots or buddings, it’s best to pass on those.
How do I store leftover creamy roast garlic and lemon pasta sauce?
Absolutely! Store any leftover sauce in an airtight container in your refrigerator for up to 3 days. When you’re ready to enjoy it again, gently reheat it on the stove over low heat. If the sauce appears thick, simply stir in a splash of cream or some reserved pasta water to bring it back to life.
Can I freeze creamy roast garlic and lemon pasta sauce?
Yes, you can freeze it! Place the sauce in a freezer-safe container or zip-top bag and store it for up to 2 months. To thaw, simply move it to the refrigerator overnight. When ready to eat, reheat gently on low, stirring often, and add a little reserved pasta water if necessary.
My sauce turned out too thick; what can I do?
Not to worry! If you find that your sauce is thicker than you’d like, simply stir in some of the reserved pasta water a little at a time, until you achieve a silky-smooth consistency. Always start with a small quantity to prevent it from becoming too watery.
Is this sauce suitable for anyone with dairy allergies?
Great question! If you’re looking for a dairy-free option, you can substitute the heavy cream with a non-dairy alternative like coconut cream or cashew cream. For the cheese, nutritional yeast works wonderfully to provide that cheesy flavor without dairy. Just be sure to check the labels to ensure they’re free from any allergens.
What pasta works best with this sauce?
The more, the merrier! You can use any pasta shape you prefer—spaghetti, fettuccine, or penne all work beautifully. If you’re looking for a healthier or lighter option, try using whole grain pasta or even zucchini noodles. Each will embrace that irresistible creamy roast garlic and lemon pasta sauce perfectly!
