Why you’ll love this casserole
This isn’t your average boxed mac and cheese. Tender egg noodles are wrapped in a velvety homemade cheddar sauce, studded with bright green broccoli florets, and topped with a golden, buttery breadcrumb crust. It’s the dish that convinces kids to eat their vegetables and adults to go back for seconds. Plus, it all comes together in one pot before baking — less mess, more comfort.
Ingredients
For the casserole:
-
12 oz (340 g) wide egg noodles
-
3 cups (about 250 g) fresh broccoli florets, chopped into bite-sized pieces
-
4 tbsp (½ stick) unsalted butter
-
1 medium yellow onion, finely diced
-
3 cloves garlic, minced
-
¼ cup (32 g) all-purpose flour
-
2 cups (480 ml) whole milk, warmed
-
1 cup (240 ml) low-sodium chicken or vegetable broth, warmed
-
2 cups (8 oz / 225 g) sharp cheddar cheese, freshly grated (plus more for topping if desired)
-
½ cup (2 oz / 55 g) Parmesan cheese, freshly grated
-
½ tsp dry mustard powder
-
¼ tsp paprika (smoked or sweet)
-
½ tsp salt (or to taste)
-
¼ tsp black pepper
-
Pinch of cayenne pepper (optional, for heat)
For the topping:
-
1 cup (60 g) panko breadcrumbs
-
2 tbsp unsalted butter, melted
-
2 tbsp fresh parsley, chopped (optional, for garnish)
Instructions
Step 1 — Preheat and prepare (Intensity: Low)
Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch (23×33 cm) baking dish.
Step 2 — Cook the noodles (Intensity: Low)
Bring a large pot of salted water to a boil. Add egg noodles and cook according to package directions until al dente (usually 7–9 minutes). In the last 2 minutes of cooking, add the broccoli florets to the boiling water. Drain noodles and broccoli together in a colander. Set aside.
Chef’s tip: Don’t overcook the noodles — they will continue to soften in the oven.
Step 3 — Make the cheese sauce (Intensity: Medium)
In the same pot (no need to wash it — more flavor!), melt 4 tbsp butter over medium heat. Add the diced onion and cook until soft and translucent, about 4–5 minutes. Add the minced garlic and cook for 1 minute until fragrant.
Sprinkle the flour over the onion mixture. Stir constantly for 2 minutes to make a blonde roux (it should look like wet sand).
Slowly pour in the warm milk and warm broth while whisking continuously to prevent lumps. Bring to a gentle simmer, whisking often, until the sauce thickens enough to coat the back of a spoon, about 3–4 minutes.
Step 4 — Melt the cheese (Intensity: Low-Medium)
Reduce heat to low. Add the sharp cheddar, Parmesan, dry mustard, paprika, salt, pepper, and cayenne (if using). Stir until the cheese is completely melted and the sauce is smooth. Taste and adjust seasoning if needed.
Step 5 — Combine (Intensity: Low)
Add the drained noodles and broccoli to the pot with the cheese sauce. Gently fold everything together until evenly coated.
Step 6 — Assemble the casserole (Intensity: Low)
Pour the noodle mixture into the prepared baking dish and spread evenly. If desired, sprinkle a little extra grated cheddar on top.
Step 7 — Make the topping (Intensity: Low)
In a small bowl, mix the panko breadcrumbs with the 2 tbsp melted butter until all crumbs are lightly coated. Sprinkle the buttery crumbs evenly over the casserole.
Step 8 — Bake (Intensity: Low — just waiting!)
Bake uncovered for 15–18 minutes, until bubbly around the edges and the breadcrumb topping is golden brown. For an extra-crispy top, switch the oven to broil for the last 1–2 minutes, watching closely so it doesn’t burn.
Step 9 — Rest and serve (Intensity: Low)
Let the casserole rest for 5 minutes before serving. Garnish with fresh parsley if desired. Scoop, serve, and watch it disappear.

Pro tips for success
-
Grate your own cheese — Pre-shredded cheese contains anti-caking agents that can make the sauce grainy.
-
Warm the liquids — Adding cold milk or broth to the roux can cause lumps and slow down thickening.
-
Don’t skip the broccoli boil — Cooking it with the noodles ensures it’s tender but still bright green.
-
Make it a meal — Serve with a simple green salad or roasted chicken for extra protein.
-
Switch it up — Swap broccoli for cauliflower, add diced cooked ham or rotisserie chicken, or throw in some sautéed mushrooms.
