💡 Tips & FAQs

Can I use ground beef?

Yes, but reduce the searing time and drain fat before adding sauce ingredients.

Can I freeze beef stroganoff?

Yes — store cooled portions in airtight containers up to 2 months. Thaw and reheat gently.

What if the sauce is too thick?

Add small amounts of beef broth until creamy consistency returns.
