The Mega Murphwich

The Mega Murphwich is our answer to that famous sandwich sauce in a can: just as quick, but with a sweet, tangy, slightly spicy homemade sauce and a lot more flavor. Brown the beef, stir in the sauce, pile it onto soft rolls, and BAM, dinner is handled.

I have never been a big fan of the flavor of the canned version, but I have always loved the idea behind it. Michelle and I wanted a super quick meal for busy nights, so we set out to create our own. It is not an exact replica, but it has the same weeknight convenience with the flavor turned all the way up.

It took us plenty of attempts to balance all the ingredients, but the final sauce hits every note we wanted: a little sweet, a little tangy, a little spicy, and deeply savory. It is unbelievably delicious and one of those meals I could eat almost every night. If you like this flavor combination, try our Cheesy BBQ Chicken Sandwich, which uses the same sauce.

This meal is perfect for hectic nights when you do not know what to cook. Serve it with fries, tots, a simple salad, or whatever easy side works for your family.

Why Add Baking Soda to Ground Beef?

Mixing baking soda and water into ground beef before cooking helps the beef retain moisture and brown more effectively. The key is to distribute it evenly and give it time to work while you prepare the sauce. It is a simple trick that keeps the beef tender instead of dry and crumbly.

What Type of Roll Should I Use?

You can use any roll you like, but the softer and squishier, the better. I like Pepperidge Farm Farmhouse Hearty Buns because they are large enough for a mega sandwich while still being soft, slightly sweet, and sturdy enough to hold the filling. Soft potato rolls, brioche buns, or regular hamburger buns all work.

Why Rice Vinegar, Mirin, and Coconut Sugar?

These ingredients may be less familiar, but each one has a purpose. Rice vinegar adds clean acidity that balances the sweetness. Mirin adds mild sweetness and depth. Coconut sugar brings a darker, caramel-like flavor, although light brown sugar works if that is what you have. The amounts are small, but together they make the sauce taste more balanced and complete.

Want to Bring It to Life Even More?

The Mega Murphwich is great as written, but diced onion and red bell pepper are easy additions that bring even more flavor, color, and texture to the filling. Cook them in the skillet before adding the beef so they have time to soften and sweeten. The sandwich is still delicious without them, so treat this as an optional upgrade.

OK, Let’s Get Cooking!

A Few Helpful Hints!

• Start with 1 tablespoon of Sriracha. You can always add more at the end if you want extra heat.
• Have the sauce completely mixed before the beef goes into the skillet. Once cooking begins, this recipe moves quickly.
• If you are using the optional onion and red bell pepper, dice them before you begin cooking.
• If you are serving fries or tots, start them before cooking the beef so everything finishes at about the same time.
