Seared & Seasoned Quarter Pound Burger on a Buttered & Toasted Sesame Bun. Topped with shredded Lettuce, Tomato Slice, long sliced Pickles and Sautéed Onions with the Flavor Packed Mustarshire Sauce that just pulls the whole Burger together.

Burger Patties

Make sure you have the Patties weighed out, portioned and frozen to be ready to go when making this recipe.

Check out my post on How to Make Burgers for more information on making Burgers. Portion the Burger Patties out at a Quarter Pound (112 g) and about 1/4 inch thick, 5 inches in diameter. Slightly bigger than the Hamburger Buns.

Quarter Pound Patties

Quarter Pound Beef Patties

  • 1 lb. of Ground Beef
  • 1 tsp Beef Powder
  • 1/4 tsp Baking Powder
Burger Seasoning

Burger Seasoning

Use this blend to season the Burger Patties when searing.

  • 1 Tbl Sea Salt
  • 1 tsp Black Pepper
  • 1/2 tsp White Pepper

Sesame Hamburger Buns

For a Quarter Pound All Beef Patty, you want larger Hamburger Buns. These by Dempsters are pretty good. After Toasting the Buttered Buns, the Pan will be hot enough to start searing the Burger Patties.

These buns are about 4.5 inches. Butter & Toast these in a skillet over medium heat.

Mustarshire Burger Toppings

The Toppings for the Mustarshire Hamburger are Lettuce, Tomatoes, Pickles and Onions with Mustarshire Sauce. Optionally add in Crispy Bacon or Sliced Cheese.

Torn Lettuce


Either tear or shred the Lettuce, using a handful for each Burger. Placed on the Bottom Bun first right after toasting the Buns.

Beefsteak Tomatoes


Thinly slice a Tomato and place on the Lettuce, using 1 or 2 slices.

Sliced Pickles


Use 1 Dill Pickle sliced, or slice it lengthwise, creating 4 long slices. Use 2 for each Hamburger.

Slivered Onions


Use about 1/4 C of White Onions chopped into Slivers. Add the Onions to the Pan right after the Burger Patties are done and removed. Briefly cook in the juices left behind from the Burgers. Place on top of the Burger Patty and Dill Pickle Slices.

Mustarshire Burger Sauce

A simple combination of Dijon Mustard & Worcestershire Sauce with Mayo for a 3 ingredient Burger Sauce that offers up really intriguing Flavors. It really does have a unique taste and to me is very familiar.

Use 1 -2 Tbl per Burger.

  • 1/4 C Mayo
  • 1/2 tsp Worcestershire Sauce
  • 1/2 tsp Dijon Mustard
Fresh Homemade Mayonnaise


Either Hellmann’s Mayo or Homemade Mayo can be used here.

Side of Air Fryer Fries

Cook up 1 lb. of Thick Cut Fries in the Air fryer to serve with these Mustarshire Burgers. Optionally with more Mustarshire Sauce to dip the Fries. You can also use Tandoori Masala for Tandoori Seasoned Fries or the Burger Seasoning for Salt & Pepper Fries.

Side of Air Fryer Fries

Toss 1 lb. of Thick Cut Fries with 1/4 C of Neutral Oil and 1/2 tsp – 3/4 tsp of Sea Salt. Toss well and place into the Air Fryer at 400 F for 30 minutes.

Let it cook for 15 minutes, then every few minutes empty the fries with oil back into a steel bowl to toss and then back into the Air Fryer. Repeat until done and crispy to your liking.

Air Fried Salt & Pepper Fries

Salt & Pepper Fries

Make as above but replace the Sea Salt with the Salt & Pepper Blend that is used to season the Burgers.
