Notes
Frequently Asked Questions
Can I Make Either Sauce Dairy-Free?
Absolutely! For a dairy-free version:
– Replace butter with vegan butter or olive oil.
– Use unsweetened almond milk or oat milk instead of cream. Add a little nutritional yeast or dairy-free Parmesan for cheesy flavor.
How Long Do These Sauces Last in the Fridge?
Both sauces can be stored in an airtight container in the refrigerator for up to 3–4 days. Reheat gently over low heat, adding a splash of milk or cream to restore their creamy texture. Avoid freezing, as the texture may separate when thawed.
What Is the Red Sauce on Pasta Called?
The red sauce on pasta is typically called marinara sauce or pomodoro sauce. Both are tomato-based, but marinara is chunkier and more rustic, while pomodoro is smoother and silkier. Other popular red sauces include arrabbiata (spicy), Bolognese (meaty), and fra diavolo (spicy with seafood).
