Easy To Make

We’ve kept these burgers really easy to make.  You’ll get all the benefit of a homemade juicy beef patty, in terms of taste and freshness, but none of the hassle.  We’re using a package of onion soup mix for all our spices and burger seasoning, and it’s the simple short cut that makes these homemade burger patties so simple to make.

Make Ahead

If you’re making them for a party make the hamburger patties up ahead of time and keep in the fridge until you’re ready to cook them.

Choosing Your Beef

You can use lean ground beef, extra lean, or medium ground beef in this recipe, whatever your preferred ground beef is.  Keep in mind that fat adds flavour.  We choose a medium for ours and they made really delicious and moist homemade burgers.

Forming Your Patties

Making homemade burger patties results in great tasting burgers.  They’re fresh and delicious, and you will definitely notice a difference from store-bought frozen ones.  They are worth the little bit more extra effort.  Keep in mind when you’re forming them that they will shrink slightly when they cook, especially if you use a ground beef with a higher fat content like medium.  Make them a little larger than your hamburger buns for the best results, and don’t make them too thick, or they’ll end up looking more like meat balls rather than burger patties once they’re cooked.

Mushroom Topping

This easy mushroom topping takes these little sliders to the next level.  There’s nothing complicated here to worry about, just tons of flavour!  

We love the classic and inexpensive white button mushrooms for this recipe, but you can always experiment with different kinds of mushrooms here.  Use your favourite, or try a combination of white mushrooms, cremini mushrooms, and portobello mushrooms.  You can’t really go wrong with fried mushrooms!

We love added some caramelized sweet onions to our mushroom mixture too.  The sweet yellow onion adds some sweetness and so much flavor, and are a great addition.

HP Sauce

There’s nothing like a great condiment to take a dish to the next level.  Every great burger needs a little sauce to elevate it.  We landed on classic HP sauce.  It’s so great used here to add a little tang.  It’s such a rich sauce that a little goes a long way.  This sauce always reminds me of my childhood, since it was a favourite of my dad’s growing up.  There’s a reason it’s a classic it adds so much to these burgers.

Other Sauce Options

Looking for some other sauce options to add to the top of the burgers?  Mayo is a great choice too.  It adds some creaminess and would be a delicious choice.  Even better would be a garlic mayo or garlic aioli.  And if you wanted to add some spice, a spicy mayo would work well here too.

Another great option would be your favourite bbq sauce.  Add smoke or sweetness to the burger with your favourite bbq sauce.

The Bun

We opted for brioche buns for our burgers and they’re the perfect choice.  They’re soft and slightly sweet, and work really well for this recipe.  Look for the slider size at the grocery store.

If you want to you could toast the brioche buns as well.  Spread each side with a little butter and place on the grill for few minutes, or in a frying pan until just toasted golden brown and serve hot.


A grilled burger is always a better burger.  It adds that smoky charred taste that we love when we think about burgers.  And if it’s the right time of year, cooking the burgers on bbq will differently be a great choice for these.  For the mushroom and onion topping, you can cook it ahead of time in a frying pan inside, use a side burner on your bbq if you have one, or use your frying pan on the grill.  Whichever you prefer.

But if you don’t have access to a bbq, feel free to cook these in a large skillet indoors on your stove.  They will still be delicious.
