I’m certain that if you love beef stroganoff that you’ll love this version: Classic Beef Stroganoff
If you’re allergic to onions then use your usual substitute (I’m assuming that you have one) or skip it altogether. I’ve been finding more and more folks lately that have an onion allergy and find it so sad. Onions are so good for you and cooking brings out their best flavor.
Another thought, one I haven’t tried but am considering, is that it may be possible to substitute ground beef sirloin for the boneless beef sirloin in this stroganoff. That would be great for those of you who might have trouble chewing.
Anyway, enough rambling on my part. Get cooking!
