FAQs

FAQs
  • What is French onion soup mix, and can I make my own?

French onion soup mix is a blend of dried onions, beef bouillon, and seasonings. You can create a homemade version by mixing dried onion flakes, beef bouillon powder, dried herbs like thyme, and a pinch of salt.

  • Can I use different types of potatoes for this recipe?

Starchy potatoes like Russet or Maris Piper work best because they crisp up nicely and absorb flavors well. Waxy potatoes might not achieve the same delicious texture.
