This ultra-comforting macaroni bake is everything you crave once the weather turns chilly. Creamy, cheesy pasta gets baked until bubbling and golden, then finished with a pile of freshly fried crispy onion rings for a playful update on the classic. It is easy to assemble and even easier to devour which makes it perfect for family dinners or quiet comfort-food nights.
I first made this when I wanted mac and cheese that felt extra special for a birthday dinner and now my family expects those crisp onion rings on every batch I make
Ingredients
- Elbow macaroni: Pick shapes that hold sauce well and look for pasta with a rougher texture for better cheese cling
- Unsalted butter: Adds richness to the sauce and helps create a silky texture
- All-purpose flour: Helps thicken the cheese sauce and make it creamy
- Whole milk: Try to use whole milk for best flavor and consistency
- Sharp cheddar cheese: Go for a strong aged cheese for big flavor I love a mature English cheddar if you can find it
- Mozzarella cheese: Melts for the signature cheese pull Opt for low-moisture mozzarella for the best texture
- Dijon mustard: Brightens and sharpens the cheese sauce
- Garlic powder: Gives a gentle savory backbone
- Salt and ground black pepper: Season carefully and always taste as you go
- Large yellow onion: Choose onions that feel firm and heavy with tight skin
- Paprika: For boosting color and a subtle smoky flavor Opt for sweet or smoked based on your preference
- Cold sparkling water: This makes a lighter onion ring batter than ordinary water
- Vegetable oil: Pick a neutral oil with a high smoke point like sunflower or canola which keeps the onion rings crisp
- Grated Parmesan cheese (Optional): Extra flavor boost for the top If using pick a block and grate it yourself
- Chopped fresh parsley (Optional): Brightens and freshens just before serving
Instructions
- Prepare the Oven and Dish:
- Preheat your oven to the right temperature and generously grease your baking dish so the pasta does not stick and you get golden edges
- Cook the Macaroni:
- Boil water and cook the macaroni just until al dente It should still have a bite as it will finish cooking in the oven Drain it well and set aside
- Make the Cheese Sauce:
- In a medium saucepan melt butter fully before sprinkling in the flour Whisk or stir constantly for about one minute until the mixture smells nutty Then begin to slowly add the milk in a thin stream whisking to prevent lumps Continue to cook and stir until the mixture thickens into a smooth sauce which should take about four to five minutes
- Add Cheese and Seasonings:
- Take the sauce off the heat and add your grated cheddar mozzarella Dijon mustard garlic powder salt and black pepper Stir until everything is melted and no flecks of cheese remain
- Combine Macaroni with Sauce:
- Tip the drained macaroni into the cheese sauce Stir to coat every noodle then scrape it all into your prepared baking dish If you like a cheesy top sprinkle with Parmesan at this stage
- Bake Until Golden and Bubbling:
- Place the dish uncovered in the center of your oven Bake for twenty to twenty five minutes until you see bubbling edges and a golden brown top
- Make the Onion Ring Batter:
- While the bake is cooking whisk flour paprika salt and black pepper together in a large bowl Pour in the sparkling water and mix just until a consistent batter forms Do not overmix
- Fry the Onion Rings:
- Heat enough oil in a deep pan to comfortably fit the onion rings without crowding Bring the temperature up to just about three hundred fifty degrees Fahrenheit Dip each onion slice into the batter gently shake off excess and fry in batches Turn the rings halfway through each batch for even color They should be deeply golden and crisp after about two minutes per side Set each finished batch to drain on a paper towel lined plate
- Finish and Serve:
- Let the baked mac cool for about five minutes to help it set Pile the onion rings on top and sprinkle with parsley if you are using Serve steaming hot with extra onion rings alongside if desired

For me the star is the sharp cheddar I love seeing those gooey cheese pockets tucked under the onion rings Every time I bake this my family gathers around eagerly and it reminds me of weekends spent at home just enjoying uncomplicated comfort food together
Storage Tips
Refrigerate leftovers tightly wrapped for up to three days For reheating cover with foil and warm in a medium-low oven to preserve the creamy texture The onion rings are best fresh but you can briefly re-crisp them in a hot oven or air fryer
Ingredient Substitutions
Feel free to swap in gluten free pasta and flour for allergy-friendly versions Swap mozzarella for more cheddar or use a smoked cheese for a deeper flavor If you do not have sparkling water regular cold water works in a pinch but the batter will be a bit denser
