This is basically Panera’s broccoli cheddar soup but in mac and cheese form. The three cheese blend makes the sauce ridiculously creamy and the vegetables keep it from being too heavy.
Cook pasta in boiling salted water for 1 minute less than package directions. Drain without rinsing.
Heat olive oil in a large skillet over medium-high heat. Add onions, carrots, and broccoli. Cook 5-6 minutes over medium heat until carrots are tender-crisp and broccoli is bright green. Set aside.
Mix salt, white pepper, garlic powder, and flour in a small bowl.
Melt butter in the same skillet over medium-high heat until foamy. Add seasoned flour mixture and whisk constantly for 2 minutes until light brown.
Reduce heat to medium-low. Gradually whisk in heavy cream, then whole milk, then vegetable broth.
Increase heat to medium and whisk for 7 minutes until thickened. Do not boil. Add dry mustard and Tabasco to taste.
Remove from heat or reduce to lowest setting. Whisk in American cheese first, then Vermont cheddar, then sharp cheddar, one handful at a time until smooth.
Add paprika and turmeric for color. Let sauce sit 5-7 minutes to thicken.
Gently fold cooked pasta into cheese sauce using a spatula. Mix in sautéed vegetables.
Serve immediately while creamy.
Notes
Do not rinse pasta to preserve starch for binding. Do not let sauce boil or it will break. Serve with crusty sourdough bread.
