Ingredients
- 8 large eggs
- 3 tbsp heavy cream
- 1 lb asparagus, woody ends snapped off, spears cut into 1 1/2-inch pieces
- 3 oz asiago cheese, shredded (about 3/4 cup), divided
- 2 tbsp butter
- 1 medium shallot, minced
- 1/2 tsp kosher salt
- 1/4 tsp black pepper
- 1 tbsp chopped fresh chives
Instructions
- Preheat the oven to 375°F and whisk the eggs with the cream, salt, pepper, and half the asiago until uniform and slightly frothy.
- Melt the butter in a 10-inch oven-safe nonstick or cast-iron skillet over medium heat and cook the shallot 2 minutes, until translucent.
- Add the asparagus and sauté 3-4 minutes, until bright green and just past raw-crisp — it finishes in the oven, so don't let it slump.
- Spread the asparagus into an even layer, pour the egg mixture over, and shake the pan so the eggs settle between the spears; scatter the remaining asiago on top.
- Cook undisturbed on the stovetop 3-4 minutes, until the edges look matte and pull a half-inch from the pan sides while the center still sloshes.
- Transfer to the oven and bake 10-12 minutes, until the center is just set with a faint wobble, like set Jell-O, and the top is pale gold rather than browned.
- Rest in the pan 5 minutes — it slumps slightly and firms enough to slice cleanly — then cut into 4 wedges and scatter the chives over.
Why this recipe works
- Stovetop start, oven finish Three or 4 minutes on the burner sets the edges while the center still sloshes, then 10-12 minutes in the oven sets the middle gently. All-stove frittatas brown the bottom before the center catches up.
- Cream in the eggs Three tablespoons of heavy cream keep the custard tender through a 375°F bake. Eggs alone tighten into rubber long before the center sets.
- Asparagus par-cooked The 3-4 minute sauté takes the raw edge off, and the oven finishes the job. Raw spears dropped straight into egg release water and weep into the wedge.
Tips for making this recipe well
Underbake on purpose
The center should wobble faintly, like set Jell-O, when you pull the pan. Carryover heat finishes it during the 5-minute rest, and a center that sets fully in the oven means an overbaked wedge.
Snap the woody ends
Bend each spear and let it break where it wants to. A knife cuts in the wrong place more often than the bend does.
Shake the pan once
Shaking settles the eggs between the spears before the bottom sets. A gap under the asparagus becomes a hole in the finished wedge.
Use a real oven-safe pan
A 10-inch cast-iron or oven-safe nonstick goes burner to oven without a thought. A pan with a plastic handle ends the plan at the stovetop.
Shred the asiago fine
Fine shreds melt into the custard; thick shreds sink or stay in strings. Split it as written, half inside and half on top.
Serving suggestions
Cut it into 4 wedges and serve it warm rather than hot; the rest in the pan is what makes the slices clean. At 3.5 net carbs per serving this works as a main course for lunch, and leftovers hold their shape well enough to pack cold. Chives go on after the rest so they stay bright. A frittata wedge travels better than almost any other main, which is worth remembering on the days the office microwave has a line.
Storage and meal prep
Refrigerate wedges in a container for 3 to 4 days. Reheat gently in a covered skillet over low heat or eat cold; the microwave works in short bursts, and egg tightens fast when over-zapped. Freezing is possible for 2 to 3 months, though the custard turns slightly weepy after thawing. Wrap wedges individually if you plan to pull one at a time, which, with 4 wedges, is the realistic pattern.
Variations worth trying
- Different cheese Parmesan or shredded provolone swaps in for the asiago by weight.
- Other vegetables Broccoli or trimmed green beans take the same quick sauté; spinach should be wilted and squeezed dry first.
- Baking-dish route Pour the eggs into a buttered pie dish and bake longer at the same 375°F if you lack an oven-safe skillet.
- Herb change Swap the chives for torn basil or parsley to match the rest of the meal.
Frequently asked questions
Can I use milk instead of cream?
You can, and the frittata sets slightly firmer and less rich. Heavy cream earns its 3 tbsp here because the oven heat is sustained.
Why is my frittata weepy under the asparagus?
Raw vegetables release water into the custard as they bake. The 3-4 minute sauté exists to prevent it, so give the spears their full time.
How do I know when it is done?
Edges matte and pulled half an inch from the pan, center wobbling faintly. A center that sloshes freely needs 2-3 more minutes; one that does not move at all went too far.
Can I make it ahead for lunches?
Yes. It holds 3 to 4 days refrigerated and eats well cold, which is rare for egg dishes this thick.
Cast iron or nonstick?
Either, as long as the pan is genuinely oven-safe at 375°F. Cast iron wants a well-buttered surface, since eggs weld to dry iron.
