Notes

1. Don’t Overmix the Meat 
Mix the ground beef just until everything is combined. Overworking the meat can make the patties dense instead of tender and juicy.

2. Shape Even Patties 
Form your steaks evenly (about 4 patties) so they cook at the same rate. Slightly flatten them for better browning and a classic Salisbury steak look.

3. Get a Good Sear 
Cook the patties in a hot skillet until a deep brown crust forms. This step builds flavor and creates those delicious browned bits (fond) that make the gravy rich and savory.

4. Use the Same Pan for the Gravy 
Do not clean the skillet after cooking the patties—those browned bits are key! They add incredible depth to your mushroom onion gravy.

5. Slice Onions Evenly 
Try to keep onion slices consistent so they cook evenly and soften nicely without burning.

6. Don’t Rush the Mushrooms 
Let the mushrooms cook long enough to release their moisture and start to brown. This enhances their flavor and prevents a watery gravy.

7. Whisk the Flour Well 
When adding flour to the pan, whisk it thoroughly with the fat to avoid lumps. Cook it briefly to remove any raw flour taste.

8. Add Broth Gradually 
Pour in the beef broth slowly while whisking to create a smooth, lump-free gravy.

9. Adjust Thickness to Preference 
If the gravy gets too thick, add a splash of broth. Too thin? Let it simmer a bit longer to reduce.

10. Taste and Adjust Seasoning 
Before serving, taste the gravy and adjust salt, pepper, or A.1. sauce as needed for balance.
