Preheat the oven to 275°F. Line a sheet tray with parchment paper and set aside.
In a small saucepan over medium-low heat, add ¾ cup unsalted butter, 1 ounce packet ranch dressing mix, 0.7 ounce packet Italian dressing mix and 1 Tablespoon granulated sugar. Heat, constantly whisking, until melted and combined (it's important you use a whisk to make sure it all combines properly.) Take off the heat.
In a large bowl, add 11 ounce box mini saltine crackers. Pour the butter mixture on top and stir to combine.
Spread the crackers in an even layer on the prepared sheet tray. If some are stacked on top of each other, that’s okay.
Bake on the middle oven rack for 25-30 minutes, stirring every 5 minutes (don't skip this step!), until light golden brown and toasty. Let cool and serve immediately.

Notes
Regular saltine crackers can be used. Just use the same amount.
Make sure you only use unsalted butter.
You can make these into "Firecrackers" by adding about a teaspoon of red pepper flakes.
