What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples or fresh summer produce that’s easy to find. If you want, you can swap a few ingredients depending on what’s in your kitchen or garden.

• Pork tenderloin or pork chops, trimmed and cut into bite-sized pieces (about 1 pound / 450 grams) – I prefer lean tenderloin for tenderness
• Olive oil (2 tablespoons) – a good quality extra virgin oil like Colavita adds a nice fruity note
• Garlic cloves, minced (3 cloves) – fresh always beats jarred here
• Yellow onion, diced (1 medium) – adds sweetness and depth
• Zucchini, sliced (2 medium) – fresh, firm zucchini works best
• Cherry tomatoes, halved (1 cup / 150 grams) – in summer, fresh is unbeatable; frozen works in a pinch
• Red bell pepper, diced (1 medium) – for a pop of color and sweetness
• Dried oregano (1 teaspoon) – or use fresh chopped if you have it
• Salt and black pepper, to taste – kosher salt preferred for seasoning control
• Shredded mozzarella cheese (1 cup / 100 grams) – optional, but I love the gooey finish
• Fresh basil leaves, torn (a handful) – added after baking for freshness

Substitution tips: If you want a dairy-free version, swap mozzarella for a plant-based cheese or omit it entirely. You can also replace pork with chicken breast or turkey if preferred. For a gluten-free meal, no worries here; this casserole is naturally free of gluten.

Equipment Needed

• Oven-safe casserole dish (about 9×9 inches / 23×23 cm) – a ceramic or glass dish works great
• Large skillet or frying pan – for quick searing the pork and sautéing vegetables
• Sharp knife and cutting board – essential for prepping the pork and veggies
• Mixing spoon or spatula – to stir everything together
• Measuring spoons and cups – for accurate seasoning and ingredient amounts

If you don’t have a casserole dish, a deep ovenproof skillet or baking dish will do just fine. I once used a cast iron pan when I couldn’t find my casserole dish, and it worked beautifully. Just be sure whatever you use is safe for oven temperatures around 375°F (190°C). For budget-friendly gear, basic glass bakeware from stores like Pyrex is reliable and easy to clean.

Keeping your knives sharp makes a huge difference in prep speed and safety—trust me, I learned the hard way when I tried chopping zucchini with a dull blade (ouch!).

Preparation Method

1. Preheat your oven to 375°F (190°C). This gives you time to prep while the oven warms up.
2. Prepare the pork: Trim any excess fat from the pork tenderloin or chops, then cut into 1-inch (2.5 cm) cubes. Season lightly with salt and pepper.
3. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Once hot, add the pork pieces in a single layer (you may need to do this in batches to avoid overcrowding). Sear for about 3 minutes on each side until browned but not fully cooked through. Remove pork from skillet and set aside.
4. In the same skillet, add remaining 1 tablespoon olive oil. Toss in the diced onion and sauté for 2-3 minutes until translucent and fragrant.
5. Add minced garlic and cook for another 30 seconds, stirring constantly. Be careful not to burn the garlic.
6. Stir in sliced zucchini, diced red bell pepper, and halved cherry tomatoes. Season with salt, pepper, and dried oregano.
7. Cook the veggies for about 5 minutes, stirring occasionally, until they start to soften but still retain some bite. You want them tender-crisp to keep that fresh summer crunch.
8. Return the seared pork to the skillet with the vegetables and stir to combine everything evenly. Taste and adjust seasoning if needed.
9. Transfer the entire mixture to your casserole dish, spreading it out evenly.
10. Sprinkle shredded mozzarella cheese evenly over the top. This adds a creamy, melty layer that’s irresistible.
11. Bake in the preheated oven for 10-12 minutes until the cheese is bubbly and golden. Keep an eye on it—ovens vary, and you don’t want the cheese to burn.
12. Remove from oven and let it rest for 5 minutes. Sprinkle torn fresh basil leaves over the top before serving for a pop of color and fresh aroma.

Pro tip: If your pork pieces seem thick, cut slightly smaller so they cook through quickly. Also, if you find the veggies releasing too much water, drain some off before adding the cheese to avoid a soggy casserole.

This method keeps the pork juicy and the vegetables lively—no mushy casseroles here, I promise!

Cooking Tips & Techniques

One of the trickiest parts of making a quick casserole like this is balancing cooking times. Pork cooks fast but can dry out if you’re not careful, while veggies want to stay crisp-tender. Here’s what I’ve learned through trial, error, and a few smoke alarms:

• Sear the pork first: This locks in juices and adds a tasty caramelized crust. Don’t skip this step even if you’re short on time.
• Use medium-high heat for veggies: This helps them cook quickly while maintaining texture. Stir often, but don’t over-stir or they’ll get too soft.
• Season in layers: Salt the pork lightly before searing and adjust seasoning after veggies are added. It builds flavor gradually.
• Cheese timing matters: Add mozzarella only at the end before baking. Putting it too early can cause it to overcook or separate.
• Multitasking tip: While pork is searing, prep your veggies so you’re ready to toss them in the pan right after. Saves minutes!
• Rest before serving: Let the casserole sit for a few minutes post-bake for flavors to meld and for easier slicing.

I once tried mixing the cheese into the casserole before baking and it turned into a gooey mess. Lesson learned: layering cheese on top is the way to go for that classic, golden crust.

Variations & Adaptations

This easy 15-minute summer pork casserole is pretty adaptable, which makes it perfect for different tastes and dietary needs. Here are a few ideas I’ve tried or thought would work:

• Vegetarian version: Swap pork for firm tofu or chickpeas for a protein boost. Add extra herbs like thyme or rosemary for depth.
• Spicy twist: Add a diced jalapeño or a pinch of red pepper flakes when sautéing the veggies for some heat.
• Low-carb option: Skip the cheese or replace with a keto-friendly cheese. Use cauliflower instead of zucchini for even fewer carbs.
• Seasonal swaps: In fall, use butternut squash cubes and kale instead of summer veggies. Adjust cooking time slightly for denser veggies.
• Different protein: Chicken breast or turkey tenderloin works just as well if pork isn’t your thing. Adjust cooking times accordingly.

One time, I swapped cherry tomatoes for sun-dried tomatoes, and it gave the casserole a deeper, tangier flavor that I didn’t expect but really enjoyed. It’s all about making the recipe your own.

Serving & Storage Suggestions

This casserole is best served warm, fresh out of the oven, with the cheese still melty and basil fragrant. I like to pair it with a light green salad tossed in lemon vinaigrette or some crusty bread to soak up the juices.

For beverages, a chilled white wine or sparkling water with a slice of lemon complements the dish nicely on warm evenings.

If you have leftovers (which is rare!), store them in an airtight container in the fridge for up to 3 days. Reheat gently in the oven at 350°F (175°C) for about 10 minutes or until warmed through. Microwaving works but can sometimes make the pork a bit tough.

Flavors actually deepen overnight, so if you don’t mind a more melded taste, try making it the day before. Just add fresh basil leaves right before serving to keep that pop of freshness.

FAQs

Can I use pork shoulder instead of tenderloin?

Yes, but pork shoulder takes longer to cook and is fattier. For this quick casserole, tenderloin or chops work best to keep cooking time short and texture tender.

Is it possible to prepare this casserole ahead of time?

Absolutely! Assemble everything up to adding cheese, cover, and refrigerate for a few hours. When ready, add cheese and bake as instructed—add a few extra minutes if cold from the fridge.

Can I freeze leftovers?

Freezing is possible but may affect the veggie texture. If you freeze, reheat gently and consider adding fresh herbs after thawing to refresh flavors.

What side dishes pair well with this casserole?

Light salads, crusty bread, or steamed green beans make great companions. For a heartier meal, roasted potatoes or quinoa also complement nicely.

How can I make this recipe spicier?

Add chopped jalapeños, a pinch of cayenne pepper, or red pepper flakes when cooking the veggies. Start small and adjust to your heat preference.
