Why You’ll Love This Broccoli Bake
- Only 3 simple ingredients
- Naturally low carb & keto-friendly
- Ready in under 35 minutes
- Crispy edges + melty cheese center
- Great alternative to heavy casseroles or potatoes
Ingredients
- 1½ pounds fresh broccoli florets (about 2 medium heads), cut into bite-size pieces
- 3 tablespoons olive oil
- 2 cups shredded cheese (cheddar, mozzarella, or a blend), lightly packed
Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 425°F (220°C).
Lightly grease a 9×13-inch glass baking dish with olive oil or cooking spray to prevent sticking and enhance browning.
2. Prepare the Broccoli
Pat the broccoli florets dry using a clean kitchen towel or paper towels.
Tip: Dry broccoli roasts better—moisture causes steaming instead of crisping.
Place the florets directly into the baking dish in a single, even layer.
3. Coat with Olive Oil
Drizzle the olive oil over the broccoli. Toss everything directly in the dish until evenly coated.
Spread the florets back out, ensuring:
- Minimal overlap
- Small gaps between pieces
This allows the edges to caramelize and crisp up beautifully.
4. Roast Until Tender & Slightly Charred
Place the dish in the oven and roast uncovered for 15–18 minutes.
Look for:
- Light browning on tops
- Slight charring on edges
- Tender stems when pierced with a knife
The broccoli should appear slightly shriveled with crisped edges.
5. Flatten the Broccoli
Remove from the oven and gently press the broccoli using:
- The back of a spoon
- A flat spatula
Flatten into a compact, even layer.
Don’t mash completely—just create a surface for the cheese to melt evenly.
6. Add the Cheese
Sprinkle shredded cheese evenly over the flattened broccoli, covering all areas.
- It’s okay if some cheese touches the dish—those bits turn into crispy, golden edges!
7. Bake Until Bubbling & Golden
Return to the oven and bake for 8–12 minutes, until:
- Cheese is fully melted
- Bubbly and lightly browned
For extra crispiness, broil for 1–2 minutes at the end (watch closely to avoid burning).
8. Rest & Serve
Let the dish rest for 5 minutes after removing from the oven.
This helps the cheese set slightly, making it easier to serve.
Scoop portions that include:
- Crispy edges
- Gooey, cheesy center
Serve directly from the baking dish for a rustic, cozy presentation.

This cheesy broccoli bake pairs beautifully with:
- Roasted chicken
