Save Mac and Cheese Stuffed Onion Rings are the ultimate comfort food mashup—crispy, golden onion rings loaded with creamy mac and cheese inside. They make any gathering instantly more fun and are just the thing when you want a snack that turns heads as well as satisfies cravings.
I first built these for a game day party when potato skins felt a bit played out and now friends beg for them at every gathering. Watching everyone light up at their first bite turned these onion rings into a house tradition.
Ingredients
- Elbow macaroni: gives you just the right chew and is easy to fill into onion rings so always look for a smaller shape with ridges
- Whole milk: helps create a creamy sauce so choose the freshest you can get
- Unsalted butter: for the base of the béchamel sauce choose a good quality butter for richness
- All-purpose flour: helps to thicken the sauce never skip sifting to avoid lumps
- Shredded cheddar cheese: for that classic sharp taste opt for medium or sharp for more flavor
- Shredded mozzarella: gives the sauce stretch and creaminess always buy blocks and shred them fresh if possible
- Dijon mustard: adds depth not heat look for a smooth mild one
- Salt and black pepper: bring balance and bring out other flavors
- Large yellow onions: become sturdy casings try to pick those that feel heavy and firm for their size
- Panko breadcrumbs: make the exterior ultra-crunchy so choose ones that feel airy and crisp right out of the bag
- Eggs and milk: bind the breading together always use fresh
- Paprika: offers color and undertones of smoke or sweetness so pick a brand whose flavor you love
- Oil for frying: look for a neutral high-heat type such as canola or sunflower
Instructions
- Cook the Macaroni:
- Cook the elbow macaroni in a large pot of well-salted boiling water just until al dente do not overcook or the pasta will not hold its shape. Drain well and set aside to cool slightly.
- Make the Cheese Sauce:
- Melt the unsalted butter in a saucepan over medium heat. Whisk in the flour and stir constantly for one minute to make a roux which gets rid of any raw flour taste. Slowly whisk in the whole milk making sure there are no lumps. Bring it to a gentle simmer stirring frequently until the sauce thickens and coats the back of a spoon this usually takes three to four minutes.
- Finish the Mac and Cheese:
- Take the saucepan off the heat and add in the cheddar cheese mozzarella Dijon mustard salt and pepper. Stir until the cheese melts completely and the sauce is smooth and glossy. Combine this sauce thoroughly with the cooked macaroni then let the mixture cool to room temperature. For easiest handling transfer to the fridge and chill for about twenty minutes until it feels firm.
- Prepare the Onion Rings:
- Peel the onions and slice them into thick even rings about one centimeter or half an inch wide. Carefully separate the rings using only the largest and sturdiest pieces. Keep any smaller inner rings for another recipe or a quick sauté.
- Stuff the Onion Rings:
- Take the chilled mac and cheese and gently press spoonfuls into each onion ring until they are full right to the top but not overflowing. Use a small spoon or your fingers to pack the mixture flat for the neatest results. Arrange the filled onion rings on a parchment-lined tray and freeze for at least thirty minutes until firm to the touch.
- Set Up Breading Stations:
- Put all-purpose flour in one wide bowl. In a second bowl whisk together the eggs with a splash of milk until smooth. In a third bowl mix the panko breadcrumbs with the paprika making sure the seasoning is evenly distributed. This setup makes coating easy and mess-free.
- Bread the Stuffed Rings:
- Working one at a time dip each frozen stuffed onion ring first in flour shaking off the excess then into the egg mixture coating all sides and finally in the panko mixture pressing gently so the breadcrumbs stick firmly. Make sure the entire surface is covered for max crunch.
- Fry the Rings:
- Pour enough oil into a deep fryer or heavy pot that it will fully submerge the rings. Heat to one hundred eighty degrees Celsius or three hundred fifty degrees Fahrenheit. Fry the coated onion rings in batches two to three minutes per side until evenly golden and crisp. Drain them on paper towels and sprinkle with a pinch of salt right away.
- Serve Fresh:
- Enjoy the rings while hot and crunchy pairing them with your favorite dipping sauces like marinara ranch or something spicy.
Save My kids always fight for the first batch out of the fryer. There is something especially fun about getting both a classic onion ring crunch and a gooey center of mac and cheese in a single bite. Cheddar cheese remains my secret weapon for boosting both taste and nostalgia.
Storage Tips
Store leftover onion rings in an airtight container in the refrigerator for up to three days. To reheat and keep them crisp use an oven or air fryer at a moderate temperature. For longer storage freeze the breaded but unfried rings in a single layer until solid then transfer to a freezer-safe container.
Ingredient Substitutions
Experiment with cheeses like Monterey Jack for a mild melt or Gruyere if you prefer a nutty punch. Gluten-free flour blends and panko work for most dietary needs. Vegans can swap out dairy for plant-based milk and cheese and aquafaba instead of eggs for breading.
Serving Suggestions
These are a dream served on a platter at parties alongside bowls of marinara spicy aioli or classic ranch. For a full meal add a green salad or coleslaw on the side. Mini versions can be made with smaller onion rings for fun finger food.
Cultural and Historical Context
