Grilled Avocado and Fontina Topped Firecracker Brats - 5

I realize the title is a mouthful, but so was the brat! A mouthful of deliciousness! HEEYYOOO!! This is the second part of a two part series where I partner with Johnsonville to kick up the bratwurst for this 4th of July. Part One was Firecracker Brats Topped with Balsamic Caramelized Onions and Feta Cheese (on a sourdough bun). In part two, I will be grilling some avocado which really amps up the flavor of the little green fruit. I also added some fontina and put the whole deal on a sweet Hawaiian bun.

Grilled Avocado and Fontina Topped Firecracker Brats Ingredients:

Let’s start with those brats:

Almost every time I go to a BBQ and someone is making brats they are doing it wrong. But brats are easy, right? Throw them on a hot fire before or after boiling them in beer. Cue the sad game show tuba. Wrong, Wrongy McWrongerson! Boiling is never allowed. Keeping brats warm in a tub of warm beer and onions is OK, boiling is not. Boiling meat is how we make water taste good, not meat. Boiling meat makes broth or soup and leaches flavor from meat. Speaking of leaching flavor. The fastest way to leach flavor from a sausage is to throw it on a screaming hot grill causing the skin to rupture. We don’t like juices leaking out of our steak, but it’s OK to let the juices of a bratwurst leak down onto the coals or burners? No it’s not. Now that we have that straight, let’s get to grilling.

I put these brats on the upper rack of my pellet smoker which was set at 225:

Mmmmmm smoky!

They take about an hour to get to 160 degrees fahrenheit internal temp, but it’s well worth the wait.

While the brats are smoking, let’s get the avocado ready. Slice them all the way around lengthwise and twist the two halves until they come apart. Then take the sharp edge of a knife and carefully bring it down into the middle of the pit like so:

Time to go pit popping

Now just turn the knife and the pit will come out clean.

Next, brush the avocado halves with olive oil:

Grease ’em up

Prepare a grill for high heat grilling (in this case a side gas grill on my pellet grill) and slap the avocados cut side down:

If you don’t get smoke the second the avocados hit the grill, the grill isn’t hot enough

Once you get some grill marks, rotate the grilled avocados to get cross hatch grill marks:

That’s right, I cross hatch my avocados!

Now let’s prep the sausages. Once they reach 160F, place the Johnsonville Firecracker Brats in the sweet Hawaiian buns and then slice the avocado lengthwise down to the rind about 1/3 of an inch wide and then push on the back of the rind until the slices of the grilled avocado come free. Place 3-4 slices on each bratwurst and then shred some fontina over the top:

Enjoy listening to firecrackers while eating Firecracker Brats this 4th of July

These brats bring some serious heat. Generally when I see something is spicy and made on the scale of Johnsonville brats, I roll my eyes as it usually isn’t that hot. These bad boys are in fact firecrackers. The buttery, grilled avocado mitigates some of that heat and allows the natural flavors of the sausage to shine. Add in the savory of the cheese and the sweetness of the bun and the flavor profile is just wonderful. There may not be a more appropriate protein for your 4th of July BBQ.
