Creamy Red Pepper Alfredo Pasta Recipe FAQs
How do I select ripe red bell peppers for this recipe?

What if my sauce comes out gritty or chunky?
This can happen if the nuts weren’t soaked long enough, so I recommend soaking them for a solid 6-8 hours—or even overnight for the best texture.

Always remember to double-check each ingredient, especially the nutritional yeast or cheese alternatives, for allergens.
