Parmesan Roasted Sheet Pan Dinner

Transform simple ingredients into a satisfying sheet pan feast with this Parmesan-crusted dinner that brings together crispy roasted vegetables with savory kielbasa, all tied together with a rich Parmesan-butter coating. This one-pan wonder has become a staple in my weekly rotation, delivering restaurant-quality results with minimal effort.

After countless sheet pan dinners, I've discovered that the key lies in proper vegetable sizing and spacing. My mother-in-law, a professional chef, taught me that giving ingredients room to breathe makes the difference between steamed and perfectly roasted results.

Essential Ingredients & Selection Tips

• Baby Potatoes: Choose firm, unwashed potatoes of similar size for even cooking. Red or golden varieties work beautifully
• Brussels Sprouts: Look for bright green heads with tightly packed leaves. Smaller sprouts tend to be sweeter
• Kielbasa Sausage: Quality matters; select pre-cooked varieties with visible spices and good marbling
• Spreadable Butter with Olive Oil: Higher smoke point prevents burning at high temperatures
• Parmesan Cheese: Fresh-grated Parmigiano-Reggiano creates the best crispy crust
• Fresh Herbs: Rosemary and thyme enhance the roasted flavors
• Sea Salt & Black Pepper: Coarse varieties provide better texture

Frequently Asked Questions

→ Can I use different vegetables?

Yes, any sturdy vegetables work well. Adjust cooking times as needed - harder vegetables like carrots need longer, softer ones like zucchini need less time.

→ Why cut potatoes into bite-sized pieces?

Even-sized pieces ensure consistent cooking. Larger pieces will need longer cooking time and may not get as crispy.

→ Can I use a different sausage?

Any pre-cooked sausage works well. Italian sausage, chicken sausage, or smoked sausage are good alternatives.

→ Do I need to flip everything?

Stirring halfway through ensures even browning and prevents sticking. It also helps distribute the flavors.

→ Can I prep this ahead?

Cut vegetables and sausage up to a day ahead. Store in fridge and season just before cooking for best results.
