Whisk marinade ingredients together in a medium bowl and toss with squash cubes.
Heat a baking sheet in the oven for 5 minutes.
Use a slotted spoon if necessary to transfer squash cubes to the heated baking sheet. Arrange so the cubes are not touching each other so the edges will become crispy. Roast in preheated oven for 10 minutes, turn squash cubes and roast for another 10 minutes.
