Ingredients

For the Casserole Layers

3 large russet potatoes, thinly sliced (about 1/8-inch thick)
1 lb lean ground beef, browned and crumbled
2 large onions, sliced and rings separated
2 large tomatoes, sliced OR 1 (15 oz) can diced tomatoes
1 1/2 green bell peppers, chopped

For Seasoning and Assembly

Kosher salt and freshly ground black pepper, to taste
Olive oil, as needed for drizzling
Butter or nonstick spray for greasing

Instructions

Preparation

1 Preheat your oven to 350°F (175°C) and generously grease a 9×13-inch baking pan with butter or nonstick spray. This step is crucial because those bottom potato layers need protection from sticking, and trust me, you don’t want to deal with scraping burnt potatoes off the bottom of your dish.
2 Using a sharp knife or mandoline slicer, slice the 3 large russet potatoes into thin, uniform slices about 1/8-inch thick. Consistent thickness ensures even cooking throughout the entire casserole, preventing some pieces from being mushy while others remain undercooked.

Building the Layers

3 Arrange the sliced potatoes in an even layer across the bottom of your prepared baking dish, slightly overlapping each slice like fallen dominoes. Drizzle generously with olive oil and season with kosher salt and freshly ground black pepper. The oil helps the potatoes develop a beautiful golden color and prevents them from drying out during the long baking process.
4 Distribute the 1 lb browned and crumbled ground beef evenly over the potato layer, making sure to spread it all the way to the edges. Season this layer with salt and pepper to taste, remembering that each layer needs its own seasoning to build complex flavors throughout the dish.
5 Layer the 2 large sliced onions with rings separated over the ground beef, creating an even distribution across the entire surface. These onions will caramelize beautifully during the 2-hour baking time, adding natural sweetness that balances the savory elements.
6 Add your tomato layer using either 2 large fresh tomatoes sliced into rounds or 1 (15 oz) can diced tomatoes drained slightly. If using fresh tomatoes, arrange the slices in overlapping rows; if using canned, distribute evenly with a spoon. Season with salt and pepper.
7 Top with the 1 1/2 chopped green bell peppers, spreading them evenly as the final vegetable layer. Give this top layer a final seasoning with salt and pepper, then drizzle lightly with olive oil.

Baking

8 Cover the entire dish tightly with aluminum foil, ensuring the edges are well-sealed to trap steam and moisture. This creates a gentle braising environment that allows all the flavors to meld while keeping the vegetables tender.
9 Bake for exactly 2 hours without opening the oven door. This lengthy cooking time allows the potatoes to become fork-tender while the other vegetables release their juices, creating a natural sauce that binds everything together.
10 Remove from oven and let rest for 10-15 minutes before serving. This resting period allows the layers to set slightly, making it easier to cut clean portions while still maintaining the distinct layer appearance that makes this dish so visually appealing.

Nutritional Information and Health Benefits

Key Nutritional Highlights:
This hearty casserole provides approximately 320-380 calories per serving when divided into 6 portions. The combination of lean ground beef and russet potatoes delivers substantial protein (about 22-25 grams per serving) and complex carbohydrates for sustained energy. Each serving contains roughly 15-18 grams of carbohydrates from the potatoes and vegetables, plus 3-4 grams of fiber from the mixed vegetables.

Health Benefits of Main Ingredients:
The russet potatoes provide essential potassium for heart health and blood pressure regulation, plus vitamin C for immune support. Ground beef supplies complete protein with all essential amino acids, iron for oxygen transport, and B-vitamins for energy metabolism. Onions contain quercetin, a powerful antioxidant with anti-inflammatory properties, while bell peppers pack vitamin C and beta-carotene. Tomatoes contribute lycopene, an antioxidant that becomes more bioavailable when cooked, supporting heart health and potentially reducing cancer risk.

Dietary Considerations:
This recipe is naturally gluten-free and dairy-free as written, making it suitable for those with common food sensitivities. It’s also nut-free and fits well into whole food eating patterns. The combination of protein, vegetables, and complex carbs makes it appropriate for balanced meal planning and family-style dining.

Smart Swaps and Ingredient Substitutions

Common Substitutions:

Russet potatoes → Yukon Gold potatoes (creamier texture) or red potatoes (holds shape better)
Ground beef → Ground turkey, pork, or lamb using same measurements and cooking methods
Fresh tomatoes → Canned diced tomatoes (drained) or tomato sauce (1 cup)
Green bell peppers → Red or yellow bell peppers, poblano peppers for heat, or sweet mini peppers

Budget-Friendly Swaps:

Lean ground beef → Ground beef with higher fat content (drain well after browning)
Large onions → Frozen diced onions (2 cups, thawed and drained)
Fresh tomatoes → Canned tomatoes (often more affordable and available year-round)

Pantry Emergency Substitutions:

Olive oil → Vegetable oil, melted butter, or cooking spray
Fresh onions → Onion powder (2 tablespoons) mixed into the beef layer
Fresh bell peppers → Frozen bell pepper strips (thawed and drained)

Pro Tips for Substitutions:

When using higher-fat ground meat, brown it first and drain excess fat to prevent greasy casserole
Frozen vegetables should be thawed and patted dry to avoid excess moisture
Root vegetables like parsnips or turnips can replace potatoes but may need extra cooking time

Make It Diabetes-Friendly

Carb Reduction Strategies:

Replace half the potatoes with thinly sliced cauliflower or zucchini to reduce carbs by approximately 15-20 grams per serving

Add extra vegetables like sliced eggplant or mushrooms to increase volume without significantly increasing carbohydrates

Portion Control Tips:

Serve smaller portions (1/8 of the pan instead of 1/6) alongside a large green salad to maintain satisfaction
Pair with high-fiber sides like steamed broccoli or roasted Brussels sprouts to slow carb absorption
Add healthy fats like avocado slices or olive oil drizzle to help stabilize blood sugar

Protein Enhancement:

Increase ground beef to 1.5 lbs to boost protein content and improve satiety
Add a layer of cottage cheese or Greek yogurt between vegetables for extra protein
Include chopped hard-boiled eggs in one of the layers for additional protein

Estimated Carb Content: Original recipe contains approximately 18-22 grams carbs per serving; modifications can reduce this to 10-12 grams per serving.

Perfect Pairing Suggestions

Beverage Pairings:
A medium-bodied red wine like Merlot or Cabernet Sauvignon complements the savory beef and rich vegetable flavors beautifully. For beer lovers, a brown ale or porter provides the perfect malty sweetness to balance the dish’s hearty nature. Non-alcoholic options include iced tea with lemon, sparkling water with lime, or apple cider for a seasonal touch that won’t compete with the complex flavors.

Side Dish Recommendations:
Crisp green salad with vinaigrette dressing cuts through the richness while adding fresh contrast. Steamed green beans or roasted asparagus provide color and crunch that complement the tender casserole layers. Cornbread or dinner rolls make excellent vehicles for soaking up any delicious juices, while coleslaw adds tangy crunch that balances the warm, comforting main dish.

Complete Meal Ideas:
Start with tomato soup or mixed greens salad as a light appetizer. Follow the casserole with vanilla ice cream or apple pie for a classic American comfort food experience. For entertaining, consider deviled eggs as an appetizer and peach cobbler for dessert to create a Southern-inspired feast.

Occasion Suggestions:
Perfect for Sunday family dinners, potluck gatherings, church suppers, and holiday meals when you want something hearty but not overly fancy. Excellent for meal prep and make-ahead entertaining since it reheats beautifully and actually improves in flavor after a day in the refrigerator.

Pro Tips and Troubleshooting

Professional Techniques:
Salt each layer individually rather than just seasoning the top – this builds complex flavor throughout the entire dish. Use a mandoline slicer set to 1/8-inch for perfectly uniform potato slices that cook evenly. Let the casserole rest 15-20 minutes after baking to allow the layers to set, making it much easier to cut clean portions that showcase those beautiful distinct layers.

Common Mistakes and Solutions:
Watery casserole usually results from not draining canned tomatoes or using vegetables with high water content – pat fresh tomatoes dry with paper towels and drain canned varieties. Uneven cooking happens when potato slices vary in thickness – invest in a mandoline slicer or take extra care with knife work. Burnt bottom layer occurs when the baking dish isn’t properly greased or the oven runs hot – use parchment paper as insurance and check your oven temperature with a thermometer.

Storage and Reheating:
Refrigerate leftovers for up to 4 days in covered containers. Reheat individual portions in the microwave for 2-3 minutes or in a 350°F (175°C) oven for 15-20 minutes until heated through. Freezing works well for up to 3 months – thaw overnight in refrigerator before reheating.

Make-Ahead Strategy:
Assemble the entire casserole up to 24 hours ahead, cover tightly, and refrigerate. Add 15-20 extra minutes to the baking time when cooking from cold. You can also prep individual components the day before – slice potatoes and store in water, brown the beef, and chop vegetables.

This five-layer masterpiece proves that sometimes the most extraordinary dishes come from the simplest ingredients, and with Dolly’s stamp of approval, you know it’s going to be nothing short of spectacular. Whether you’re feeding a crowd or just want to treat your family to something special, this casserole delivers comfort, flavor, and satisfaction in every single bite.
