For the Spinach Sauce
• Baby Spinach – The star of our vibrant hue; use fresh spinach for the best flavor.
• Fresh Herbs (e.g., parsley, basil) – They enhance the flavor profile; dried herbs can be a quick substitute if needed.
• Garlic Powder – Adds depth; fresh garlic works well if you prefer a bolder taste.
• Onion Powder – Infuses the sauce with savory goodness; can be swapped for finely minced onion.

Step‑by‑Step Instructions for St. Patrick’s Green Mac & Cheese
Step 1: Prep the Pasta
Begin by cooking the macaroni according to the package instructions, but aim to slightly undercook it to prevent mushiness. Once tender but firm, drain the pasta and set it aside for later. This step is crucial, as the macaroni will absorb some moisture while baking in the creamy St. Patrick’s Green Mac & Cheese.
Step 2: Make the Spinach Sauce
In a blender, combine the baby spinach, fresh herbs, garlic powder, onion powder, and milk. Blend everything until you achieve a smooth, vibrant green sauce. The freshness of the spinach adds both color and nutrients, making this St. Patrick’s Green Mac & Cheese a delightful and wholesome choice for the family.
Step 3: Prepare Cheese Sauce
In a large pot over medium heat, melt the butter until bubbling. Whisk in the flour to create a roux and cook for about 2 minutes, stirring continuously until it’s light golden. Gradually add in the milk, whisking until the sauce thickens and becomes creamy. Stir in the sharp cheddar and mozzarella, blending well until completely melted and combined.
Step 4: Combine
Now, gently stir the vibrant spinach mixture into the cheese sauce, creating a beautifully creamy base. Next, fold in the cooked and drained macaroni, ensuring every piece is well-coated with the luscious sauce. This mix of flavors and textures is what makes the St. Patrick’s Green Mac & Cheese a festive highlight at your table.
Step 5: Assemble
Pour the combined mac and cheese into a greased baking dish, spreading it evenly. In a separate bowl, mix breadcrumbs with melted butter, then sprinkle this crunchy topping over the macaroni mixture. Season lightly with salt and pepper to enhance the flavors before baking, ensuring that every bite is deliciously satisfying.
Step 6: Bake
Preheat your oven to 350°F (175°C) and slide the baking dish in once ready. Bake for approximately 20 minutes, or until the top is golden brown and crispy. You’ll love the bubbling cheese action beneath the crunchy surface, which indicates that your St. Patrick’s Green Mac & Cheese is perfectly cooked and ready to be devoured.
Step 7: Serve
After removing the dish from the oven, let it cool for a few minutes to set the flavors. Serve warm, and savor the joy of this comforting dish that’s not only beautiful with its vibrant green color but also wonderfully creamy and cheesy. Enjoy your delightful creation fresh from the oven for the best texture!
