Place potatoes in a single layer on a large microwave-safe plate. Microwave on high power for 2 minutes. Flip potatoes over and continue to microwave about 2–3 minutes longer. (If potatoes are larger, they’ll take a couple of minutes longer; pierce each potato once with a fork if needed.) Potatoes should be tender. Let cool slightly, then cut in half and in half again to get quarters.
While potatoes are cooling, finely chop the shallot and chop the red pepper.
Add 1 tablespoon oil and 1 tablespoon butter to a large, heavy-bottomed pot (12 inches or larger). Heat to medium, and as soon as the butter is nearly melted, add the shallot. Stir for 1 minute and add garlic; stir for about 20–30 seconds. Lower heat if either are cooking too quickly. Add remaining 1 tablespoon olive oil, paprika, garlic powder, onion powder, and chopped red pepper. Cook, stirring occasionally with a wooden spoon, for 3–4 minutes.
Meanwhile, slice sausage into coins on the diagonal. Push red pepper to the side and add remaining 1 tablespoon butter and potatoes. Cook for 2–3 minutes to crisp up potatoes and coat all ingredients.
Push everything to the side, add in sausage, and cook another 2–4 minutes, until all oil/butter is fully absorbed, veggies are crisp-tender, and sausage is heated through. Season to taste with salt and pepper. (I add about 1/2 teaspoon salt and 1/4 teaspoon pepper.) Increase any spices as desired. (Spices can greatly vary based on brand, so you might want more.)
Serve with freshly chopped parsley and sauce(see note 1)if desired.
Notes
Note 1: To make the creamy Dijon sauce, whisk together 1/3 cup whole grain (or stone ground) Dijon mustard, 3 tablespoons mayo, and 1 tablespoon freshly squeezed lemon juice. (This sauce is likely more than you’ll need for this dish unless you like a lot of sauce, so feel free to halve the ingredients.)Nutrition Note: Nutritional information does not include Parmesan cheese or Dijon sauce.Storage: Move the leftovers to a container with a tight seal. Keep in the fridge for up to 3-4 days.
