Step-by-Step Instructions

Preheat the Oven:
Set your oven to 350 degrees Fahrenheit 175 degrees Celsius so it is hot and ready when it is time to bake
Brown the Turkey:
Place a large skillet over medium high heat and pour in olive oil When the oil shimmers add ground turkey Break up the turkey with a spoon and cook for about five minutes stirring often until it is mostly browned with just a little pink left
Sauté the Vegetables:
Add the chopped onion and minced garlic directly to the browned turkey Continue to cook for two minutes stirring frequently until onions begin to look translucent and the garlic releases its aroma Stir in the diced zucchini and keep cooking for three to four more minutes until the zucchini just starts to soften at the edges
Combine Everything:
To the skillet add cooked groats diced tomatoes oregano smoked paprika fresh basil and half your shredded cheddar cheese Mix thoroughly so everything is evenly coated and the groats begin to take on the tomato flavor
Assemble and Top:
Lightly grease a large 9 by 13 inch baking dish with more olive oil or cooking spray Pour the turkey and vegetable mixture into the prepared dish and spread it out into an even layer Sprinkle the rest of the cheddar cheese evenly over the top
Bake the Casserole:
Transfer the dish to the oven and bake uncovered for about 20 to 25 minutes or until the top is bubbling and golden brown Let cool for five minutes before serving so slices hold together

The smoked paprika in this dish made all the difference for me After I gave the recipe a twist with smoked paprika instead of regular I had new appreciation for its depth My kids now ask what makes it taste so good every single time

Storage Tips

Let any leftovers cool to room temperature before covering and refrigerating for up to four days Slice squares for easy microwave reheating For longer storage wrap well and freeze up to three months then thaw fully in the fridge before warming in the oven

Ingredient Substitutions

This recipe is so accommodating If you do not have ground turkey try lean ground chicken or even beef For groats you can use cooked quinoa brown rice or even barley to suit your taste If you skip cheddar use any firm melting cheese like Monterey Jack or Swiss

Serving Suggestions

Serve this casserole hot with a crisp green salad some crusty bread or even a dollop of Greek yogurt on top I sometimes spoon leftovers into tortillas for a quick lunch wrap the next day It also pairs beautifully with grilled vegetables or a simple cucumber tomato salad

Recipe FAQs

→ Can I use a different type of ground meat?

Yes, you can substitute ground turkey with chicken, beef, or even plant-based crumbles for a different flavor.

→ What grains work well besides groats?

Brown rice or quinoa are excellent alternatives, offering similar texture and absorbing seasonings well.

→ How can I add more vegetables?

Bell peppers, spinach, or mushrooms can be included for extra color and nutrition without altering the core flavor.

→ Can the casserole be made ahead?

Definitely. You can assemble, cover, and refrigerate or freeze the dish, baking it when ready to serve.

Any sharp cheddar or your favorite melty cheese will work, but Kerrygold adds a rich, distinctive taste.

Sauté the zucchini until it begins to soften but isn’t mushy. Draining excess liquid before baking also helps.
