How to Make Homemade Dairy Free Hamburger Casserole

Step-by-Step Cooking Instructions

Step 1: Heat oven to 375°F (190°C). Grease a 9×13-inch baking dish. Bring a large pot of salted water to a boil and cook pasta until just al dente. Drain.

Step 2: Warm olive oil in a large skillet over medium heat. Add onion and cook 3–4 minutes until soft.

Step 3: Add ground beef. Cook, breaking it up, until browned. Drain excess fat if needed.

Step 4: Stir in garlic, bell pepper, and mushrooms. Cook 2–3 minutes until fragrant.

Step 5: Add tomato paste, diced tomatoes, tomato sauce, Italian seasoning, paprika, salt, and pepper. Simmer 5 minutes. Stir in dairy-free milk and half of the cheese shreds. Add cooked pasta and toss to coat. Taste and adjust salt.

Step 6: Spoon mixture into the baking dish. Top with the remaining dairy-free cheese. Cover with foil and bake at 375°F (190°C) for 15 minutes, then uncover and bake 10 more minutes until bubbly.

Step 7: Let it rest 10 minutes so it sets. Garnish with parsley. Serve warm.

Tips for Texture, Timing & Tools

• Undercook pasta by 1–2 minutes; it will finish in the oven.
• If sauce looks dry, add 1/4 cup pasta water or broth.
• For extra creaminess, stir in 2 tbsp nutritional yeast or dairy-free cream cheese.
• Use an oven-safe skillet to go from stove to oven and cut dishes.
• Rest before slicing to keep neat squares and less steam loss.

Storage & Reheating

How to Store It Right

• Cool to room temperature (about 1 hour).
• Refrigerate in an airtight container up to 4 days.
• Freeze whole or in portions up to 3 months. Wrap tightly to prevent freezer burn.

Reheating Without Losing Flavor

• Oven: 350°F (175°C), covered, 15–20 minutes (whole), 10–12 minutes (portions). Add a splash of dairy-free milk or water if dry.
• Microwave: Reheat portions 60–90 seconds, stirring halfway.
• From frozen: Thaw overnight, then reheat as above. Or bake from frozen at 350°F (175°C) for 40–50 minutes, covered.

Can I make this ahead?
