🍽What Do I Serve With This Casserole Dish?

Fresh Green Salad

A fresh green salad is the perfect companion to this casserole. The crispness of the greens adds a refreshing contrast to the richness of the dish. Toss together some mixed lettuce, cherry tomatoes, cucumber slices, and a light vinaigrette for a simple yet satisfying side.

Garlic Bread

Garlic bread is another excellent accompaniment. The buttery, garlicky flavor pairs wonderfully with the savory casserole. Plus, it’s great for soaking up any leftover sauce on your plate. You can easily make garlic bread at home by spreading a mixture of butter, garlic, and parsley on slices of baguette and toasting them until golden and crispy.

Roasted Vegetables

To add more veggies to your meal, consider serving the casserole with a side of roasted vegetables. Carrots, Brussels sprouts, and zucchini are all great options. Simply toss them with olive oil, salt, and pepper, and roast in the oven until tender and caramelized. The natural sweetness of the roasted vegetables complements the savory casserole beautifully.

⏲️Chef's Tip

Use Fresh Ingredients

For the best flavor, use fresh, high-quality ingredients whenever possible. Fresh garlic, onions, and bell peppers will give your casserole a more vibrant taste compared to their canned or powdered counterparts.

Customize Your Spices

Feel free to adjust the spices to suit your taste. If you prefer a spicier dish, add extra chili flakes or a dash of hot sauce. For a milder version, reduce the amount of paprika and chili flakes.

Make It Ahead

This casserole is perfect for meal prep. You can assemble it the night before and store it in the refrigerator. When you’re ready to bake, simply pop it in the oven. This makes it a convenient option for busy weeknights when you want a homemade meal without the hassle.
