Full Step-by-Step Recipe
1. Prepare the vegetables
Wash and dry all vegetables.
Cut the peppers, tomato, mushrooms and zucchini into bite-sized pieces.
For a dish that looks particularly similar to the photo, keep some of the pepper pieces relatively large rather than finely chopping everything.
2. Brown the beef
Heat a large skillet over medium-high heat.
Add the ground beef and cook for approximately 6–8 minutes, breaking it apart with a wooden spoon.
Cook until browned and no longer pink.
Drain excess grease if necessary.
USDA data specifically recognizes that ground beef’s nutrient profile varies substantially according to its lean/fat percentage and cooking method, so the nutrition below is an estimate rather than a laboratory-tested value.

3. Add onion and garlic
Add the diced onion and cook for about 3 minutes.
Add garlic and cook for another 30–60 seconds.
4. Season
Add:
paprika
Italian seasoning
chili powder
salt
black pepper
onion powder
Worcestershire sauce
Stir thoroughly.
5. Add the vegetables
Add the mushrooms, zucchini and peppers.
Cook for 4–5 minutes, stirring occasionally.
You don’t want the vegetables completely soft because they will continue cooking in the oven.
6. Add tomato
Stir in the diced tomato and tomato sauce.
Simmer for 3–4 minutes.
Taste and adjust the salt and pepper.
The finished mixture should be flavorful but not extremely watery.
7. Assemble
Lightly grease four small oven-safe foil baking dishes, or use a 9 × 13-inch baking dish.
Divide the beef-and-vegetable mixture among the dishes.
Sprinkle mozzarella evenly over the top.
Add cheddar and Parmesan.
For the appearance in your photograph, don’t completely cover every vegetable—the exposed peppers and browned cheese give it that characteristic look.
8. Bake
Place the dishes on a sturdy baking sheet.
Bake at 400°F / 200°C for 15–20 minutes, until the cheese is completely melted and bubbling.
For a darker golden top, switch to broil/grill for 1–3 minutes at the end.
Watch it closely because cheese can burn quickly.
9. Rest and serve
Remove from the oven and let stand for 5 minutes.
Serve hot.
A little chopped parsley, cilantro, green onion or fresh basil makes a nice finishing touch.
Best Cheese Combination
For the closest combination of stretchy + creamy + browned cheese, use:
Mozzarella + cheddar + Parmesan
If you want a milder version:
Mozzarella + Monterey Jack
For a stronger flavor:
Mozzarella + sharp cheddar + Parmesan
For extra browning:
Add a small amount of Parmesan to the very top during the last 5 minutes.
Approximate Nutrition
Etimated using the ingredients above and divided into 4 servings. Actual values will vary with the beef’s fat percentage, cheese brands, amount of vegetables and how much beef fat is drained. USDA FoodData Central is the appropriate reference database for food-composition estimates, and USDA notes that ground-beef nutrition changes with its fat percentage and preparation method.

Why the numbers can change
Using 90% lean beef instead of 80–85% lean beef can substantially reduce calories and fat. Likewise, reducing the cheese from 2¼ cups total to 1½ cups will lower calories and saturated fat.

Lower-Calorie Version
For approximately 450–500 calories per serving:
Use 90–93% lean ground beef
Use 1 cup mozzarella instead of 1½ cups
Use only ¼ cup cheddar
Increase mushrooms and zucchini
Drain the beef thoroughly
Use cooking spray instead of additional oil
You’ll still get a cheesy topping while increasing the vegetable volume.
Higher-Protein Version
Use:
1¼ lb (570 g) 90% lean ground beef
1½ cups mozzarella
½ cup cottage cheese mixed into the beef filling, optional
The cottage cheese melts into the filling and adds protein without making the finished dish taste strongly of cottage cheese.
Spicy Version
Add:
½–1 tsp crushed red pepper
1 diced jalapeño
½ tsp smoked paprika
Pepper Jack cheese in place of some cheddar
You can also add a few drops of hot sauce to the beef mixture.
Low-Carb / Keto Notes
This recipe is naturally relatively low in carbohydrates because it contains no pasta, rice, bread or potatoes.
To reduce carbs further:
Use extra mushrooms, zucchini and peppers.
Use an unsweetened tomato sauce.
Check the tomato sauce label for added sugar.
Avoid serving it with bread, rice or pasta.
The approximate 14 g net carbs per serving above comes mainly from the vegetables and tomato sauce.
Want the Dish More Filling?
Add one of these underneath the beef mixture:
Potato
Use about 2 cups par-cooked diced potatoes.
Rice
Add 1½ cups cooked rice.
Cauliflower rice
Add 2 cups cooked cauliflower rice for a lower-carb option.
Pasta
Add 2 cups cooked pasta and increase the tomato sauce slightly.
If adding a starch, the nutrition values above will change substantially.
Recipe Q&A
Can I use ground turkey instead of beef?
Yes. Ground turkey works very well. Choose 93% lean turkey for a leaner version. The flavor will be milder, so smoked paprika, garlic, Worcestershire sauce and extra herbs are helpful.
Can I use chicken?
Yes. Finely chopped chicken breast or ground chicken can replace the beef. Cook ground chicken thoroughly before assembling the casserole.
Can I make this without mushrooms?
Absolutely. Simply replace the mushrooms with extra zucchini, peppers or onions.
Can I use frozen vegetables?
Yes, although fresh vegetables give the best texture. If using frozen peppers or other vegetables, thaw and drain them first so the casserole doesn’t become watery.
Can I prepare it ahead of time?
Yes. Assemble the casserole, cover and refrigerate for up to 24 hours before baking.
When baking directly from the refrigerator, it may require several additional minutes.
Can I freeze it?
Yes. Cool completely, package airtight and freeze.
For best quality, use within approximately 2–3 months.
Thaw overnight in the refrigerator before reheating.
Can I make this in one large casserole dish?
Yes. A 9 × 13-inch baking dish works well.
Bake for approximately 20–25 minutes, or until hot and the cheese is bubbling.
Why is my casserole watery?
The most common causes are:
Vegetables releasing water.
Too much tomato sauce.
Not draining the cooked beef.
Using frozen vegetables without draining them.
Cook the vegetables briefly before assembling and avoid adding excess sauce.
How do I get the browned cheese shown in the picture?
Bake until the cheese melts, then use the oven’s broiler/grill for 1–3 minutes.
Stay next to the oven and watch continuously—the cheese can go from golden to burnt very quickly.
What temperature should the beef reach?
For ground beef, use a food thermometer and cook to 160°F / 71°C. USDA ground-beef data and preparation guidance distinguish ground beef by both fat level and cooking method.

Can I use only mozzarella?
Yes. Mozzarella gives the longest cheese pull. Adding cheddar or Parmesan gives more flavor and browning.
Is this gluten-free?
The basic recipe can be gluten-free, but check the labels of Worcestershire sauce, tomato sauce, seasonings and cheese if you need strict gluten avoidance.
Is it dairy-free?
No. The standard recipe contains mozzarella, cheddar and Parmesan. Use a dairy-free shredded cheese alternative if necessary.
What are the main allergens?
The standard recipe contains milk/dairy.
If using Worcestershire sauce or packaged tomato sauce, check the ingredient label for additional allergens or dietary restrictions.
What should I serve with it?
Good choices include:
Green salad
Steamed broccoli
Roasted cauliflower
Garlic green beans
Avocado
Coleslaw
Cauliflower rice
Can I put the foil trays directly on the oven rack?
It’s safer to put them on a rimmed baking sheet. Small foil trays can flex when filled with hot food, making them difficult and potentially unsafe to remove.
Best Version for the Photo
If your goal is to reproduce the look of the pictured dish, I’d use:
85–90% lean ground beef + red/yellow/green peppers + tomato + mushrooms + onion + zucchini + mozzarella + cheddar + Parmesan, with the vegetables kept fairly chunky and the cheese browned under the broiler at the end.
The photo alone can’t establish the exact original ingredients or quantities, so the recipe above is an image-inspired reconstruction, not a claim that these are the original recipe’s ingredients. USDA’s FoodData Central is useful for adjusting the nutrition calculation when
