The Complete Shopping Rundown
- 14 ounces rigatoni pasta
- 2 tablespoons extra virgin olive oil
- 4 cloves garlic, minced
- 1 small red onion, thinly sliced
- 1 red bell pepper, large chunks
- 1 orange bell pepper, large chunks
- 1 small zucchini, chopped
- 1 small eggplant, chopped

- 16 ounce can tomato sauce
- 1 cup crumbled feta cheese
- 1 cup shredded mozzarella cheese
- Spices: 2 teaspoons dried oregano, 1 teaspoon dried basil, ½ teaspoon dried thyme, ½ teaspoon sweet paprika, ¼ teaspoon crushed red pepper flakes, ½ teaspoon sea salt, ⅛ teaspoon black pepper

You’ll wanna grab these together so you’re all set to toss, roast, pressure cook, and bake without missing a step. The olive oil helps everything crisp in the oven, and the garlic plus herbs gives you that kinda warm and cozy flavor. Chopping the vegetables into similar size chunks helps 'em cook evenly too.
The Exact Process From Start to Finish
- Preheat your oven to 400°F (200°C). This gets your veggies ready for their caramelizing moment.
- Cook rigatoni pasta in a big pot of salted boiling water until just al dente. Drain it and set aside so it doesn’t get mushy later.
- In a large bowl, toss the chopped red onion, bell peppers, zucchini, and eggplant with minced garlic, olive oil, oregano, and basil. Make sure everything’s well coated.
- Spread those veggies evenly on a baking sheet and roast in the preheated oven for about 20 minutes. Give them a good stir halfway so they brown evenly.
- Now mix your roasted veggies right into the cooked rigatoni in a large baking dish. Pour in the diced tomatoes and tomato sauce. Blend it all up well.
- Lock your pressure cooker’s sealing ring in place and set the pasta bake inside. Cook on high pressure to allow pressure build for about 5 minutes. Use quick release to stop cooking and keep veggies firm.
- Stir everything up, then sprinkle on crumbled feta and shredded mozzarella. Pop it under the broiler for about 5-7 minutes or until cheeses melt and get all bubbly.
- Let the pasta bake cool for a few minutes before serving so the flavors settle and it’s easier to dish out.
Time Savers That Actually Work
- Use pre-minced garlic if you’re really pressed for time. It still works real good for flavor.
- Buy pre-chopped veggies from your grocery store to skip the cutting step.
- Cook your rigatoni pasta in the pressure cooker itself before the veggie roast to save on pots.
- Mix the cheese in last minute instead of waiting until after the initial cooking. That way it melts perfect.
- Prep the spices as a blend ahead so you don’t gotta measure each time.
When You Finally Get to Eat
When you dig in, each forkful hits you with roasted goodness and that bright tomato sauce wrapping everything up all cozy. The softness of the pasta with chunky veggies gives you this hearty, stick-to-your ribs kinda vibe.
The feta brings that salty tang that cuts through the mellow sweetness from the roasted peppers and zucchini. Melted mozzarella adds a gooey, dreamy texture that kinda sticks around on your tongue.
You sense the oregano and paprika dancing gently underneath, giving it a little warmth without being spicy. It’s the kinda comfort food that makes you wanna sit down and savor, even if you’re usually on the run.
Plus your kitchen’s gonna smell like this cozy Mediterranean bistro, making you feel like you scored something special without all the fuss.

Your Leftover Strategy Guide
- Refrigerate: Store leftovers in an airtight container and keep ’em in the fridge up to 3 days. Warm gently so you don’t dry it out.
- Freeze: This bake freezes well. Portion it out in freezer-safe containers. Thaw overnight in fridge before reheating on low heat.
- Meal Prep: Pack this up in your lunchbox cold or reheat at work. It holds up well and still tastes great the next day.
Keeping the pasta bake from drying is key when storing. Adding a little splash of water when reheating keeps everything nice and moist. Label your containers so you keep track and don’t forget about your tasty leftovers!
What People Always Ask Me
- Can I use other pasta types? Totally! Penne, ziti, or even fusilli work great. Just watch the cooking time since some shapes cook faster.
- What if I don’t have hatch or fire roasted tomatoes? You can swap regular canned diced tomatoes. It won’t have that smoky touch but still tastes great.
- Can I make this vegan or dairy-free? Yep, just skip the feta and mozzarella or use plant-based cheese alternatives.
- Is it okay to roast veggies in the pressure cooker too? Roasting in the oven helps caramelize and build flavor. The pressure cooker is better for softening quickly without drying out.
- How do I know when pressure’s done? It usually takes a few minutes to pressure build. Your cooker’s manual will give exact timing. Once done, quick release stops the cooking right away.
- Why sprinkle cheese last? Adding cheese at the end under the broiler keeps it melty and golden. If you cook it too long under pressure, it might get rubbery.
