Roasted sausage, potatoes, and onions

Mmm this was tasty and easy, another 'made while in France' recipe.  I took inspiration from another recipe I have with Kielbasa sausage which is one of my favorites for a quick and simple dinner back home.  I didn't measure anything, so that is why all the amounts have question marks by them.  I plan to try this back in the States, with perhaps Italian sausage or Kielbasa.  10/10.  p.s. the little white chunk at the top part of the bowl is a piece of fresh goat cheese I had with it :) 

Ingredients: 

1.5 lbs. (?) red potatoes, cut in bite-sized pieces
3 T. (?) unsalted butter
1 T. (?) olive oil
1 medium red onion, cut in half cross-wise, then each half cut in half, sliced thin (you will have half-circles when slices separate)
salt and pepper, to taste
granulated garlic (1/2 tsp.?)
paprika (3/4 tsp.?)
thyme (1/4 tsp.?)
4 Diot sausages, sliced in slightly less than 1/2" rounds

Directions: 

1. Line a medium baking sheet with aluminum foil.  Heat oven to 375°F (honestly, not terribly sure about temp...)

2. In a microwave safe bowl, cook potatoes (uncovered) on HI power for 8 minutes.  Be careful when removing from microwave!

3. Stir in butter and olive oil, then mix in the sliced red onion.

4. Season with salt, pepper, garlic, paprika, and thyme, stirring to mix well/combine.

5. Pour mixture onto prepared baking sheet.  Nestle sliced sausage pieces evenly throughout mixture on sheet.

6. Transfer to oven and bake for 35-40 minutes, stirring about halfway through.  Serve up and enjoy!
