Switch the oven on to 400°F (200°C). Get 2-3 small ovenproof dishes or ramekins ready, and put them on a baking tray to make moving them around easier.
02 -
Warm up the olive oil in a skillet over medium heat. Toss in the onions, mushrooms, and green peppers. Cook them for around 4-5 minutes, stirring occasionally. Mix in the garlic and cook for one more minute, but be careful not to burn it.
03 -
Push the veggies to one side of the skillet, creating space. Add the ground beef or turkey, season it with salt, pepper, and Italian seasoning. Break it into smaller bits while stirring, cooking until browned and fully cooked (about 5-7 minutes). If needed, remove any extra grease.
04 -
Pour the marinara sauce into the skillet and mix well. Let it simmer for a couple of minutes so the flavors combine and the sauce thickens a little. Taste and adjust seasoning if you like.
05 -
Scoop the meat and veggie mixture into the ramekins evenly. Leave a little space at the top for cheese. Sprinkle Parmesan and mozzarella generously over each. If you want, sprinkle on some red pepper flakes for extra spice.
06 -
Put the tray with the filled ramekins into the heated oven. Bake for about 10-12 minutes, or until the cheese turns golden and bubbly.
07 -
Once out of the oven, let the ramekins sit for 2-3 minutes to cool slightly. Add some fresh parsley or basil on top before serving. Be careful—the ramekins will stay hot for a while.
