🥄 Step-by-Step Instructions

Step 1: Prep potatoes and broccoli

• Boil cubed potatoes until fork-tender—about 10–12 minutes. Drain.

• Steam broccoli until just tender but still vibrant—2–3 minutes. Drain and set aside.

Step 2: Sauté onion & garlic

• In a skillet, melt butter or heat oil. Sauté onion until translucent, then add garlic and cook briefly until fragrant.

Step 3: Make cheesy sauce

• In a saucepan, stir in flour to make a roux, then whisk in milk until smooth.

• Add shredded cheese (reserve about ½ cup for topping), sour cream, mustard (if using), salt, and pepper. Stir until melted and creamy.

Step 4: Combine casserole

• In the baking dish, layer potatoes, chicken, and broccoli. Pour cheese sauce evenly over the top. Sprinkle remaining cheese.

Step 5: Bake to perfection

• Bake at 180 °C (350 °F) for 20–25 minutes, until bubbly and lightly golden on top.

Step 6: Garnish & serve

• Let it rest for 5 minutes before serving. Garnish with parsley or chives for a fresh pop of color.

💡 Pro Tips for Success

• Don’t overcook broccoli—you want a little crunch to balance the textures.

• Use full-fat dairy for a richer sauce, but lighter options work too.

• Let it rest before digging in—this helps everything set nicely.

• Make ahead tip: Assemble and refrigerate, then bake right before serving.

---

🧊 Storage Instructions

• Refrigerator: Store covered for up to 4 days. Reheat in the oven or microwave until warmed through.

• Freezer: To freeze, bake first then cool completely. Wrap tightly and freeze for up to 3 months. Reheat from frozen—just add extra baking time.

Can I skip the roux and just mix cheese into milk?
Technically yes, but the roux gives the sauce smooth texture and prevents separation.

Absolutely—just omit the chicken and add more veggies or beans.

Stir in a splash of milk until you reach your desired consistency.
