What’s In This Oat Milk Mac and Cheese Recipe?
- Oat Milk: which you can make yourself with some water and old fashioned oats, steel cut oats, or rolled oats – NOT quick cooking ones. The quick cookinig oats get slimy and that is not what you want in your pancakes. Old Fashtioned Oats are the perfect texture – I use Bob’s Red Mill variety because they are certified gluten free. If you don’t want to make oat milk youself, this unsweetened oat milk has the perfect texture for this mac!
- Macaroni Noodles: to make this gluten free, these awesome GF macaroni pasta noodles work perfect in this recipe. If you aren’t gluten free, then you can use normal macaroni, whole wheat, or a veggie pasta.
- Olive Oil: I like to use this delicious Zoe olive oil which has a fantastic flavor and deep color- it’s really inexpensive online here, so I keep a few liters stocked up in my pantry. For the quality of oil you get, it’s an excellent value, I would highly recommend!
- Mustard Powder: for a sonderful sharp flavor, I like this mustard powder best!
- Salt: We like to use pink himalayan sea salt which has more minerals that normal table salt (and is a great value for the price!)
- Pepper: like salt, I only use really good pepper corns, I like these tellicherry pepper corns because they have a fresh spicy taste when they are ground. There are a lot of varieties but I like Amazon’s generic tellicherries best for the value.
- Cheddar
- Melty Cheese: You can use creamy Velveeta for this recipe, or another melty cheese alternative. You can use a plant-based cheese for a vegan substitute as well.
- Parmesan Cheese: for a bright and sharp finish on this mac! I love adding this parmesan cheese to my mac and cheese recipes to give it that little extra kick of flavor.
