Make Stuffed Onions
I’ve a type of obsession with stuffing. Not Thanksgiving stuffing (OK, possibly that, too), however stuffing meals with much more scrumptious elements! I’ll stuff absolutely anything, from jambalaya stuffed peppers to eggplant and mushrooms.
Whichever veggie I select, the tactic is kind of the identical. Right here’s find out how to put collectively these saucy Italian sausage stuffed onions:












- Trim and steam the onions. Begin by trimming ¼” from the highest of the onions, and trim the underside in order that the onions stand upright. Then, microwave the onions in two batches with a little bit water in order that they steam and soften (in my microwave, it takes about 12 minutes per batch).
- Hole out the center. As soon as the onions are cool sufficient to deal with, use a pointy knife to fastidiously reduce out the center layers of every onion, leaving about ¼” thickness across the edges. Chop up and put aside about 1 cup of the eliminated onion for the filling. Save the remaining for a stir-fry, salad, or frittata!
- Fill the pan. Now, unfold tomato sauce into the underside of a greased casserole dish. Organize the onion shells over the sauce. Give {that a} fast season with salt and pepper.
- Put together the sausage filling. In the meantime, brown the sausage in a skillet. Add garlic and the reserved chopped onions, adopted by tomatoes, the remainder of the tomato sauce, ½ cup of cheese, and breadcrumbs. Stir every thing collectively.
- Stuff the onions. To stuff your onion shells, spoon a little bit of filling into every onion. It’s wonderful if a little bit spills out right here and there, however do your greatest.
- Bake. Lastly, cowl the baking dish with the stuffed onions in foil. Bake at 375ºF for 15-20 minutes, and as soon as they’re heat and bubbly, sprinkle the tops of the onions with the remaining cheese. Tada! Baked stuffed onions, able to serve.


Suggestions and Variations
- Use the correct onions. I extremely, HIGHLY advocate candy onions for this recipe. Whereas yellow or brown onions will work in a pinch, the flavors aren’t fairly the identical. Candy onions have a a lot milder taste. Additionally, with regards to onions, be sure you choose onions related in measurement. This manner, they’ll cook dinner by way of evenly.
- Steam in batches. Use a microwave-safe dish, and microwave the onions in batches. Make certain there’s about ½ cup of water in every batch in order that they steam.
- Save the pan sauce! All that tomato sauce left over within the baking dish is scrumptious to drizzle over the onions when serving.
- Swap the sausage. Rather than Italian sausage, you should utilize plain floor turkey, rooster, floor beef, or pork. Should you’re utilizing common floor meat, I like to recommend including in a couple of pinches of Italian seasoning to style, to spice up the flavors. You could possibly additionally borrow the meat mixtures from my pork meatballs and air fryer meatballs.
- Completely different cheese. Any melty cheese works nice on this recipe. Should you don’t have an Italian mix, substitute it with shredded cheddar, Monterey Jack, Gouda, or Swiss cheese. I believe a French onion soup-inspired variation crammed with savory floor beef and topped with Gruyère cheese could be scrumptious!
- Extra add-ins. Customise the filling any manner you’d like with mix-ins like capers, olives, pine nuts, spinach, and herbs like oregano, basil, rosemary, thyme, and Italian seasoning. Should you like a bit of additional kick, add crushed chili flakes or cayenne.
