• Cook pasta according the package instructions. When there is a bout 1.5 minutes left on your pasta timer, add frozen green peas straight into the boiling water and boil together for the remaining cook time.
• Drain pasta and peas and then pour back into the cooking pot. Set aside on the counter.
• While the pasta is cooking, melt butter in a small sauce pan. Add 2 tbsp of flour and cook over medium/medium high heat for 1 minute.
• Turn the heat down to low and slowly stream in 2 cups of milk while whisking continuously to get rid of any lumps.
• Turn heat back up to medium/medium high heat and cook while whisking frequently for 6-9 minutes until thick and bubbly.
• Remove from heat and add in white cheddar cheese. Stir until smooth. Add in salt, pepper, mustard and onion pepper. Stir to combine.
• Pour cheese sauce over the cooked pasta and peas and gently fold to combine.

Add a crispy top (optional)

• Transfer the mac-n-cheese to an oven proof dish or skillet.
• Turn the oven on the broil setting.
• Sprinkle the top of the pasta with 2-3 tbsp panko bread crumbs.
• Broil for 2-4 minutes until the breadcrumbs brown and get cripsy. Be sure to keep an eye on it as it can burn easily.
• Remove from oven and sprinkle with fresh chopped parsley. Enjoy!
